I removed mcafee and have noticed overall that I have almost double the memory available on our 32 bit 4gig PS 4.5 server as another identical server with McAfee installed.

The issue that we are finding is that when users are connected to a virtual server (Either from XenServer, VMWare, or Provisioning Server V-disk), the users local D: drive maps, but not the local C: drive. Initially, I believed this to be a user profile issue, so we cleaned the profiles and that did not resolve the issue. When the user connected to a physical server, the drive mapped properly. This only happens when they are connected to the Virtual Servers. This doesn't seem to be specific to either Provisioning Server, or VMWare.

Any & All assistance with this matter is greatly appreciated.Read more:Group: Tech Support ForumsForum: Virtualization + Server-Based Computing]]>Wed, 03 Sep 2008 08:33:38 GMT102449Virtualization + Server-Based Computinghttp://www.brianmadden.com/Forum/Topic/102402
My question is simple. Lets say a user has centain customizations done to the applications loaded already on there profile, ( cad stuff or Email for their signature, etcs). In therory each time the user logs onto a fresh desktop, they will need to configure that or have IT (ME) configure it.

Is there a script or way that can see how the user customizes their desktop and mimic on each or any other fresh desktop for ther profiles. That way the user will never truely know if they are on the same machine?

That is my question. Maybe I missed something, but thats my question! Any help would be great!!!Read more:Group: Tech Support ForumsForum: Virtualization + Server-Based Computing]]>Mon, 01 Sep 2008 10:50:45 GMT102402Network Performance / WAN Optimizationhttp://www.brianmadden.com/Forum/Topic/102274
I am in the process of on boarding a new application into an existing PS4.5 environment which will be accessed from the server and delivered to a new site. I am wondering if and how it is possible to profile how much bandwidth a session will place on the link for the new application?

Is there a general rule of thumb that peopple generally use here?

Since moving to four 8-core terminal servers (citrix win2003x64) we now see 100% cpu utilization much of the time with around 55 users. Four times the cores, not even twice the users.

I have moved the citrix servers into the same network as my exchange server to negate the netscreen's interference - no dice. I have removed the static port mappings on exchange and the GCs since they are no longer necessary without the firewall inbetween - no dice.

Any ideas? Could it be some interaction between outlook and x64 windows? Could it have been some outlook patch that is making it spin its wheels? It is taking users 20-25 seconds to open emails during these periods of spiking. External clients using rpc/http (in online mode) do not have this issue, and the Exchange server (also 8 core) isn't even breaking a sweat, so it seems to be something on the outlook side.

any ideas would be greatly appreciated, i'm losing a lot of sleep on this one!!

If I wanted to see what the Load was on a given CPS box at a given time, what utility could I use to do that? I thought this was built in, but I'm starting to believe otherwise now.

I'm having an issue where users at a particular location cannot do session sharing. All other users in other locations all have the same Session ID when they open up multiple sessions published on the respective servers. I dont think its a client version issue because all the users have different versions ranging from 9 to 10. The servers are configured exactly the same way. I had to set the terminal server to 'Restrict each user to one session'. After making this change, each of their sessions have different Session ID's and they also wind up launching the multiple sessions that span more than one server. The other users are still able to do sessions sharing after this change. Any ideas?Read more:Group: Tech Support ForumsForum: Citrix Presentation Server / XenApp]]>Thu, 24 Jul 2008 10:16:22 GMT101436Terminal Serviceshttp://www.brianmadden.com/Forum/Topic/101378 than the privious day.

I don't know if this makes a difference but the all the users are connected via vpn connection and the server is located in a datacenter. There is a AD server in both locations. I have the My Documents folder mapped from the Datacenter to the main office( I am almost certain this is not good???)

Any help would be greatly appreciated.

I would like to utilize the XenDesktop Premium. My thought is to use the Ardence, (Stream via PXE) on all my existing workstations and clients to log into the vitural machine. I would like to set 2 new servers (Either virtually or physcially for the DDC and the Provision Server). I would like to create 2 template (which I can do updates, and install new softwares on the OS and applications). I can provision them ON-DEMAND as a user would log on. This way, It would keep the VM Clean and the VM FAST for performance. AS for the clients, If the PXE boot would possibly Fail, The user can log into the local hard drive and use either Linux Based OS or the OEM Windows and connect to his VM Via Remote Desktop Connection. (This method could poissbly used in a WAN or Home experience as well, I hope!)



I have tested Xendesktop on a setup. However, the biggest thing I am looking for are the graphics. I am looking into the Apollo Project with Citrix to help boost the performance of the graphics so I can deliver CAD like Experience to the client from the Server.

On the flip side. I have tested or testing the SPICE, SolidIce Setup. We like it, however, there are a few things which Xendesktop offer we like, which SolidIce does not have. We like the idea of a diskless client (PXE Boot). We like the On-Demand Provisioning of fresh desktops to our users. However, SPICE Graphics are way better than Xendesktop SpeedScreen, but still not like a Local Workstation Setup.

I hope my idea is not to out of the way, I think this is possible... Any thoughts would be great!

I suspect I already know the answer to this, but I would like to have it confirmed.

We have in out existing farm, 4 PS4.0 RO5 servers.

The hardware is:
IBM x335
2x dual core zeon 2.4ghz (32bit)
2.39ghz 2.50gb ram
raid 0
1 Gb nic

We're running Windows 2003 standard SP1

We have approx 30 sessions on each server, this is a mix of published apps and published desktops.

The users are continually saying that Citrix is slow, and by this they mean, typing has a lag, applications are slow to launch, and slow to change when you're working in them.

What I'd like confirmed is for the specified hardware, what would you generally expect the MAX number of sessions/users to be before performance is noticably degraded, and what would YOU do to improve the performance.

Thanks

I have a Presentation Server 4.5 farm that has been running stable for about 8 months that is now exhibiting a strange issue.

Some of the servers at random stop allowing connections to applications and when you RDP to them you see the following error in the Application Log:

Reliability Server
Unable to connect to the CGP tunnel destination (127.0.0.1:1494)

The only solution seems to be to reboot the server and it is fine again after the reboot for an unknown amount of time.

From what I have been able to find, people suggest rebooting to temporarily fix the issue or remove session reliability.

Anyone else run into this problem and have a better solution?

Thanks,

I am the currently looking into migrating my current 32bit environment to a 64bit environment with 32bit apps. My current environment is below. My initial plan was to use several DL 385's 2 AMD CPU Dual Core servers with 12GBs of RAM to accommodate about 180 users. Adding more memory will probably not be a problem but getting more servers will be - budget constraints. Given the data below, realistically, how many users could I support on one server with the given profile below?

Regards,

Ian

My Environment:

2 HP DL740G1 4 Xeon's, 16gb RAM, 2 RAID 1 Volumes (C: O/S, Page File, Spool Files) (D: User Profiles, Apps, Page File)

1 HP DL360 Pentium III Session Directory Server

O/S - Windows 2003 SP2
Applications - Microsoft Office & Navision (Microsoft ERP)

I average 80 users on each DL740 with current usage as follows:
75-80 users running Navision ERP
10-15 users running Outlook
2-5 users running Access
10-15 users running Work
10-15 users running Access
1-3 user running Powerpoint

Printer drivers installed include: HP LaserJets, Deskjets, Canon Inkjets, Xerox Work Centers/Document Centers

Performance statistics as follows:
totals
handles - 232475
threads - 5365
processes - 859

phyiscal memory
total - 16776448
available - 11050788

We often get complaints of the performance, particularly from our Branch offices. What is strange about that is as soon as we (IT Support) shadow in to try and investigate these issues, they IMMEDIATELY go away. The shadower can do everything in normal time and the shadowee can see (and do) it happening in normal time with more than respectable performance.

In addition to this, generally (but not always) the performance issues re-appear as soon as the shadower disconnects.

Can anyone shed any light on why this might be the case?

Thanks!

My question/issue is in regards to roaming profiles/folder redirection and the slow selection of fonts within Outlook. Has anyone ever had an issue when composing a new email or changing the font in any Microsoft product when using roaming profiles/folder redirection? Currently, I have users logging into a PS4.5 box using folder redirection and roaming profiles. All these users experience a 30+ second delay when trying to change the font. Any help would be appreciated.

Thanks,

Background:

Our current farm is win2k3 SP1/PS XP. Running $ Gb of memory.

Our ERP app is odd in that when you pull up sub applications and close them it keeps them in memory so the memory footprint of the app quickly baloons over the course of the day (from ~30Mb too 100-150 Mb)

I am migrating the old servers too PS 45, and adding a Win2k3R2 Ent server with 16 Gb of memory to the load balance group.

In my testing I am seeing 2 things

1) There is a bit more paging on the new server, from ~25 pages/sec on the old server too ~40 on the new server
2) The ammount of memory per session is actually less on the new server (From 95Mb avg too ~ 70 Mb). this is a rough calc based upon free memory/# of sessions


My question is this:

Has anyone else noticed a difference in how the enterprise memory manager handles paging in comparrison to standard? I guess it could be PS45 as well.

I can look at the working set of the app process for each session to see if it is paging more, but it would take alot of playing in perfmon to get an accurate assessment of this. If anyone knows for sure or could point me to any articles on the memory manager differences it would be very helpful.
