Ok this what happened last week we lost power to the office but for some reason we have about a dozen Pc that lost there IP address the system is set up for PC to obtain there on IP address I have renew and release the IP it does release but after the user shuts down they get this new address of 10.0.0.30 does any one now why the OS are win2k and xp all together there are about 1000 pc. And the only way we are able to get them back on the network is to assign them IP

I would check your DHCP server to make sure it rebooted properly or that the IPs havent been locked in some way.

Moving to Hardware.

also bear in mind that if the number of PC's you have is very close to the macimum number of addresses your DHCP server provides.. it may be that the DHCP server still thinks some addresses are in use.. the lease may not have expired on the server.. and it will therefore not assign those addresses to any other computer

this is further backed up by the fact that you only seem to be able to get one IP address on a /renew..

you could always add another subnet to the DHCP server.. see if that makes a difference
