We try to open a Virtual Channel on a Windows Server 2012 with WTSVirtualChannelOpen(WTS_CURRENT_SERVER, WTS_CURRENT_SESSION, "name").
The function always hangs for 10 seconds and returns NULL. Afterwards called GetLastError returns 0x80004005 (unspecified error).
This problem only happens on Server 2012, the same code works without problems on Server 2003 and 2008, using the same client.
Firewall is disabled (personal and domain).
- Did anything change between Server 2008 and Server 2012 that would cause such an "unspecified error"?
- Is there any way to get more detailed information on the cause of the error (e.g. activate logging on WTS... functionality)?
Any answers are appreciated ...
Andreas
