Server 2008R2 Terminal Server Black Screen

Hello,

I have a 2008R2 Terminal Server, sometimes when users connect from outside (never internal) they get prompted for the credentials and then presented with a black screen that after 2-5 seconds disconnects them.

I am seeing no errors in applications, but occasionally event ID 50 & 56 in system.

All windows update, latest drivers and bios.

Tried various fixes including disabling RSS & Chimney from TCP.

BUT.....

If when the black screen appears you press CTRL-ALT-END, the desktop appears and you can carry on as normal!

Any suggestions welcome..

Hi guys

I have finally fixed the issue.
The problem was caused my the MTU setting on both the WAN interface of the firewall (sonicwall) and the LAN card in the terminal server.

I lowered the MTU on the WAN interface to 1300 and create a regdword in the registry on the NIC card to lower the MTU to 1300 also.

Happy Days!

Its a known bug and Microsoft has been working on it.

In the mean time just keep using our good old friend CTRL-ALT-END

Arrrrgh.

Thats fine for me, but the explaining it to the customer is another story :-)
Is this detailed somewhere that I can point to the customer to?

A.
