Re: RDP no Longer working (Internal / External)

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I have had this on a couple of sbs server recently after installing MS
updates and the server restarted. After checking ports and a number of other
things I ended up just restarting the server and it worked again. Let me
know if that doesn't fix it.

Hi All,

We have been battling a server that has recently decided that it no longer
wants to allow connection via RDP either as a console re-direct or general
request.

Unable to connect to RDP from inside network.
RWW responds with:
---------------------------
Microsoft Internet Explorer
---------------------------
Connectivity to the remote computer could not be established. Ensure that
the remote computer is on and connected to the Windows Small Business
Server
network.
---------------------------

RWW RDP Connection is possible to XP workstations following resolving the
NLA issue.
(http://blogs.technet.com/sbs/archive/2007/04/24/common-networking-issues-after-applying-windows-server-2003-sp2-on-sbs.aspx)

We have already checked all of the usual culprits / ports etc, but am a
bit
stumped by what is causing the problem, we have so far tried:

Setting NLA to Automatic (As it was set to Manual) - This then allowed
connection to Workstations internally.
Tried connecting to http://192.168.0.20/tsweb to check web connectivity,
downloads ActiveX control and attempts connection
Looked through the Blogs regarding NLA & RDP connectivity issues, all
seems
to be OK.
VPN is working fine, with access to all network resources.
Checked for conflicting services, Sites etc that may be using the same
port
- but cannot find any.
All Automatic Services are Started.


We have tried re-booting a few times to see whether this resolves the
issue,
and cannot see any errors in the Event Logs.

Server is a:
1. Windows SBS 2003 R2
2. Windows 2003 SP2
3. Exchange SP2
4. WSUS

Does anyone have any ideas on finding the problem, or maybe seen this
before.

Thanks in advance.

Paul.
