We have recently deployed XenApp 6.5. We have a at least one user that when using the mobile app or on the desktop receive this error "the task you are trying can’t be completed because Remote Desktop Services is currently busy" This issue continued for some time before allowing the user access.
After looking into why this happened I have found no errors in logs or any where else. Test accounts seem to work fine connecting on both the mobile or pc.
We have applied the latest hotfix packs and as detailed Hotfix pack 2 had a fix for this issue.
We have also checked the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI
to a longer time.
Any idea what would cause this and any solutions to this issue?
