Digi Classic PCI Board on Win 2K Server, Microsoft driver Update

I have 3 WIN 2K (all with Service Pack 4) servers with digi Classic PCI boards. Last week I did a windows update that included a driver update for the cards.
After the install of the update my digi board had changed their com ports from 3,4,5,6 to 7,8,9,10.
I tried to change them back in the digi board congif but it says that ports 3,4,5 and 6 were already in use.

The driver updates in not uninstallable in the Add/Remove programs list.

Try this link. It worked for me.
