Strange Internet Connectivity Problems

Specs: Windows Server 2003
Hi everyone, i thought these forums look nice and friendly so i thought i would post my problem here.

Im running: Windows Server 2k3 SP2

The problem:
I have a strange intermittent internet connectivity problem where my server browser wont work and my game servers that i run wont connect to the masters and also my SQL database server wont work.

However it still does have internet connectivity as i can connect to it using VNC (its a rented server) people still on the game servers stay on there and my website works using IIS just nobody can login because SQL doesnt work.

This is a very strange problem i cant seem to fix by repairing the connection updating drivers etc.

The server uses manually configured IP settings as it runs game servers and must have a static IP.

Cheers for anyone who replies :)

I would start by looking in Event Viewer for error messages. Have a look through there and report back what, if any, error messages you find.

Thanks for the reply,

There isnt much all that i can see within the last 24 hours or so that might have something to do with it is this error entry in System:
Error entry from WBLS:

NLB Cluster : Cluster mode cannot be enabled due to parameter errors. All traffic will be passed through to TCP/IP. Restart cluster operations after fixing the problem by running 'wlbs reload' followed by 'wlbs start'.

For more information, see Help and Support Center at

Then straight after that an information entry from IPSec:

The IPSec driver has entered Secure mode. IPSec policies, if they have been configured, are now being applied to this computer.

For more information, see Help and Support Center at

This error i can see a number of times usually once a day as much as this error occurs, im not sure if it happens at the exact time this error does id have to wait until it does it again.

Does that give any help or not?

Cheers again,

hmmmm.....interesting issue. I had hoped for something a little more indicative in the event viewer logs.

think it might be a DNS issue since DNS isn't required when you connect via VNC, or gamers connect to the game servers, the same way DNS is necessary for say, the web browser on the server to connect to websites. You might want to take a look at the server's DNS IP settings and ensure those are correctly assigned.

Other than that, I can't think of what may be causing this intermittent issue. If nobody else jumps in with ideas, you might want to try posting this over in the Windows 2003 forum here at
