Hi @dirkdigs
Are these users performing a proper logoff when completing their sessions? It's quite common for default printers to be lost if users don't log off gracefully.
As a possible remedy if they are logging off properly, I would recommend you first install all the available hotfixes on the Print Server.
Then try add the following registry value :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider\RemovePrintersAtLogoff = 0 (DWORD)
Also, perform the steps mentioned below:
Open registry with psexec -i –s c:\windows\regedit.exe
Delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider" and then Re-Create it (empty)
Add under Client Side Rendering Print Provider "RemovePrintersAtLogoff" / 00000000
Export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SWD\PRINTENUM\PrintQueues , delete PRINTENUM Key it, then re-create it, then Import again all the Exported Items of PrintQueues
Do the same step for HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\SWD\PRINTENUM and HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\SWD\PRINTENU
Restart the Server
I hope this answers your question.
Thanks.
