Load Balancing in WINNT 4.0 TSE/Citrix

I currently have Citrix-Metaframe 1.8 installed on WINNT 4.0 TSE sp6. Two of my Servers disappear from Load Balance Administration without any warning.

As a result, no more connections are accepted through published Apps, and the ICA Browser Service hangs and the process cannot be ended from Task Manager or at a Command-Line.

Restarting the servers seems to be my only option to get them back into Load Balancing.

No luck on Citrix’s Knowledgebase. Does anyone have any idea’s?

Thanks,

Jeff C. Watts
