Endpoint format is invalid trying to RDP to server

Hello,

I recently rebuilt a backup server from the ground up and have started getting the following error when trying to RDP into the computer:
Logon Message
The system cannot log you on due to the following error:
The endpoint format is invalid.

Please try again or consult your system administrator.

The server is running WSS2003R2 with BackupExec 2014 (latest patches and SP's). Any ideas about what could be causing this issue?

As a side note - it worked fine for about two days then quit working again... Don't know what's going on - I haven't done a THING different!

Maybe this will help.

ast night we finally uninstalled the Symantec Endpoint Protection on those two servers and the problem disappeared.  It seems that when I upgraded from SEP 11.0 to SEP 12.1 on our AntiVirus server, these two servers (out of twelve servers and 90 clients) didn't like having the SEP 11.0 client.  Again, after removing the old SEP client from these two servers -- I even had to run Symantec's CleanWipe utility on one of them -- the problem disappeared from both servers.

Hello Randy,

And thank you so much for taking a look at my question!

I did see that EE post before I posted my question - my server does not have SEP installed, so it *shouldn't* be the reason this problem is happening.

The only things I've got installed on that server are Windows Storage Server 2003R2, all Windows Updates, Symantec BackupExec 2014, and all BackupExec 2014 updates. I believe that Symantec installs their updater utility too, but aside from that this server is pretty clean!

I hope I can get somewhere with this problem! Thanks again for the response!
-Duane

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SystemPages it should be Decimal 31000

if not then from safe mode edit the registry entry and reboot

Hello David,

I checked that location and could not find a key with the name "SystemPages", however there is a key named SystemPages in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

The value is 0. Should I change this one instead?

Thanks!
