RDP conflicts with UVNC?

RDP conflicts with UVNC?

Postby Zimbu » 2009-09-01 17:43

I have UltraVNC 1.0.6.5 installed on a 32-bit Windows Server 2003 R2 (SP2). UltraVNC server is running as a service. Currently using the Mirror Driver, but the same issue happens without it.

When I connect with UltraVNC viewer, everything is great.

If someone connects using RDP to a new session (not the console session - just a new RDP session), UltraVNC stops responding. The viewer can see the console, and if I walk over to the box and use the physical console, the viewer can see the graphics updating, but inputs from the viewer no longer work.

When the last RDP session closes, UltraVNC starts working properly again.

Any idea why RDP would be interfering with UltraVNC? Again, this is a secondary session, NOT the console session that the user is accessing via RDP.

I could have sworn this setup used to work with the older versions of UltraVNC. Has something changed in the newer versions that's causing this problem?

Well, I eventually managed to figure out what the problem was, and figured I should post an update in case anyone else runs into a similar problem.

Kaspersky Antivirus was running on the server, and was interfering with UltraVNC. The weird thing is that it wasn't interfering with UltraVNC until someone accessed the server via Remote Desktop.

I disabled Kaspesky's option to protect itself against remote control programs, and now UltraVNC is working properly even if people access the server via Remote Desktop.
