After installing the Hotfix KB893066 on a Windows 2000 Advanced Server,
the ADS is no longer reachable by the clients. Communication is done
through the TCP/IP Protocol on all machines.

This Hotfix changes the 'tcpip.sys' file, so maybe there are some
important changes in it?!

After uninstalling the Hotfix everything works fine as before.

Does anybody else have this problem or a possible solution?
