I'm trying to troubleshoot a small Xendesktop 7.1 deployment. Users are getting
frequent gray screens (re-connection from session reliability) up to 10 a day and randomly when typing the text is about 2-3 words behind.
Same users who connect to a terminal server and run the same programs do not have either issue. Many times these users are working right next to each other and only the VDI
desktop user is affected.
This seems to only occur on users who connect to a non persistent Win7 VDI desktops. The specs are very high on each desktop and things seem to run pretty fast until you start typing but even then its only random, happening about 70% of the time.
This issue is driving me crazy. I have examined event logs on the virtual desktop and the Xendesktop controller. I have tried migrating the effected machines onto different ESX hosts (both ESX 5.1 and 5.5) and different storage tiers on the EMC SAN. No luck.
I disabled GPU acceleration in Office 2013.
I have checked storage latency. All OK.
I have verified it is not an internet connectivity or latency issue.
I have applied the default WAN optimized template to the delivery group in Citrix Studio.
Not sure what else to check. I am still very new to Xendesktop 7.1 and would appreciate any recommendations.
