Server keeps losing license info, in the Citrix XenApp / Presentation Server forum on BrianMadden.com

I have a single farm with the license server located at the main office and 15 metaframe servers across 4 offices.
I have one server that keeps losing it's license info and users cannot logon. I see errors 9026, 19, 9014 and 9018 in the system log.

The workaround is to reboot the server or in the CMC point the server to a ficticious license server and then repoint to the correct one.
Anybody has a permanent solution, I am thinking to remove it from the farm and put it back.

Thanks
