Our Win2000 based DHCP server has all of a sudden stopped allocating IP addresses to Win95/98/ME clients. But it is till functioning for Win NT clients. What could have gone wrong?

You don't give us much to go on.

What error messages are you seeing.

Things to check:

1. Is the scope large enough to handle all computers seeking IP addresses?
2. What is the length of the lease? If you have a long lease time, there may be computers no longer on the network with active leases. If the NT clients are more or less static, but the Win9x clients come and go (laptops maybe), the NT clients will ALWAYS get a new lease (their old one will be renewed), while the mobile (or infrequently connected) computers will be first-come, first-serve (this also ties into having a large enough scope).
3. Have you made any changes to DHCP configuration recently (based on the assumption that Win9x clients could previously get a DHCP lease)?

In DHCP have you added a BootP forwarding agent. If you do DHCP stops handing out addresses. Perhaps you inadvertantly did. Check your DHCP configuration and all BootP references.
