RDP is Hanging if on-access is enabled

Hi folks

For some time now a we're heaving difficulties starting an rdp session.

It is taking ages to show the credentials window when starting mstsc.exe.

As soon as we disable On-Access Scan the window will be shown immediately.

As soon as we restart it's hanging again.

I cannot competely reconstruct it though.

Not all PC are affected eventhough they have the same policy, agent, vse and dat.

The issue seems to be similar to this one:

Does anyone have an idea how to fix this?

Windows 7 x64 Enterprise

Agent 5.0.1.516 

VirusScan Enterprise 8.8.0.1385

Engine Version 5700.7163

DAT 7903.0000

MCDATREP1000 1.0.3.368

No updates seem to be available so far.

I've pushed policy and agent on affected and not affected pc without any difference

kind regards Chris

Re: RDP is Hanging if on-access is enabled

Can you report on the what occurs when you experience the issue, and then do this -

- immediately close the MSTSC window

- immediately run it again

Because, it sounds like you're merely encountering some lag in response to the EXE file being scanned.

Most files are scanned in milliseconds, but certain files can and do take longer to scan depending on circumstances. So if the test results in fast access when launching it the second time, then it'll solidify that we're dealing with a scan taking place.

It looks like you are absolutely right.

When I close the credentials dialogue and reconnect the dialogue appears right away.

Also tested it for different target computer. It is working pretty good as long as the remote connection window stays open.

So it seems to be a general issue then

Just found this article: McAfee KnowledgeBase - Performance issues with specific applications after installing VirusScan Ente...

It looks like I'll have to add an exlusion until an update will be available
