Network Load Balancing drops out intermittently

[pehi]

Hi - I'm experiencing really strange behaviour from our terminal server cluster running Network load balancing. It seems to work fine for approx 24 hours, then drops out for no visible reason. The individual nodes remain fine, but the Cluster IP address stops answering from remote subnets.

If I then uninstall and reinstall the NLBS service, it works again.

Pehi,

You say when it fails, you cant access it from remote subnets, does that mean that you can ping it from the local subnet.

That's correct.

We have now tried putting a dumb hub in front of the switch, with both TS's patched into the hub, the hub then patched into a single switch port. We still get the same scenario - remains fine for a period of time, then drops out - it seems to be when several connections are made it falls over.
