We are using a DHCP server on cisco switches (types 6509, 3550, 3560, 877). We distribute options 78 en 79 (SLP directory agent and SLP scope). Sometimes when we start the workstation, the tree or server cannot be found. Sometimes it takes a minute or two before the client receives (or queries) the dhcp server for the slp options. Sometimes the client never receives the options. The day afterwards all is fine.

Client 32 version we are using is 4.91 SP4.

I get the idea it is a timing issue with the DHCP components.

Any idea's were to start troubleshooting, of other people having the same issue ?
