WSAEWOULDBLOCK when logging into SAP via VPN

Hi

When trying to log in to SAP via a VPN, I get the error:

partner '10.x.x.x:sapdp02' not reached

WSAEWOULDBLOCK: Resource temporarily unavailable

I feel that I read almost all the other posts on SCN but still I can't find an answer.

Here is what I can tell you, and what I've tried so far. Any other suggestions?

The SAP server is up.

We've tried connecting with the same credentials from a different machine and it works. Thus the problem is either with my network or my PC.

I've been able to login to that server before from my PC succesfully.

I cannot ping the server.

I cannot open a telnet session to 10.x.x.x 3402, nor on port 3602.

I've tried to connect with different network setups: 3G, wireless, cable - all give the same result.

I've disabled my local firewall and antivirus.

What else can I try?
