Running Netware 5.1 and Windows XP Pro; Client 4.9 SP1a. After upgrading
to new systems, we began having problems with database sharing. Further
investigation reveals the following error:

"Your computer was not able to renew its address fromthe network (from the
DHCP Server) for the Network Card with network adress xxxxxxxxxxxxxx. The
following error occurred:

The semaphore timeout period has expired. Your computer will continue to
try and obtain an address on its own from the network address (DHCP)

We've made all updates possible, and attempted to disable opportunistic
locking and client-side caching, to no effect.

Thanks for any suggestions!
