Vista Connection problems to Windows Server 2003 R2

[PhilL]

Hello,

I have a brand new Dell laptop with Windows Vista Business. I've installed
SP1 as well. I have a VPN setup to connect to various customer servers for
support purposes. I can connect remotely to Windows Server 2003 but I cannot
connect to Windows Server 2003 R2 servers from my Vista laptop. I can connect
perfectly with my older XP Pro laptop.

I have connection problems to the 2003 R2 servers using the following
software:
Remote Desktop
Windows Explorer
SQL Server Management Studio 2005

I can ping the external IP's of the servers successfully.

All the above work fine when connecting to 2003 servers (non R2) with my
Vista laptop.

The errors I receive are as follows:

Windows Explorer: "Windows cannot access \\xxx.xxx.xxx.xxx"

Remote Desktop:
I get a blank Remote Desktop screen (without login screen) and then error:
"Your Remote Desktop session has ended.
The connection to the remote computer was lost, possible due to network
connectivity problems..."

SQL Server Management Studio 2005:
I can get a connection once in a while but it does not last. When I setup
the connection and press the 'Test' button, it connects fine.
Most of the time I get the following error:
"A transport-level error has occurred when receiving results from the
server. (provider: TCP Provider, error: 0 - The specified network name is no
longer available.) (Microsoft SQL Server, Error: 64)

I think all the above problems are related and probably have to do with the
setup on the Windows Server 2003 R2 servers. I've tried with my Firewall off
and on - no difference.

I can connect perfectly with my older XP Pro laptop.

Thanks in advance,

Phil

Can you telnet 2003 R2 port 3389? You may need to enable telnet on the
Vista.

Hi Robert,

From my Vista machine:

I can Telnet to all servers on port 3389.
I can ping all servers.

When I try "net use" to the IP's of the Windows Server 2003 R2 I get the
following:

System error 53 has occurred.
The network path was not found.

When I try the same thing with just a Windows Server 2003 it works fine.
All the above commands work successfully to all servers on my XP Pro machine.

So I thinks it’s a network problem rather than a remote desktop problem.

Any help you can give would be greatly appreciated.

Phil

Is it possible the vista is multihomed computer?

I don't believe so. There is only 1 NIC in the Vista machine and only one
0.0.0.0 default route in the routing table.

I solved the problem finally.
The problem was with my Linksys VPN RV042 router. I changed the MTU setting
to 1500 bytes and everything works perfectly.

Thanks for you help,
Phil
