When traveling from site to site do you know if they are booting up their computers or do they just suspend them? Depending on your lease duration on your DHCP server the the computer may not be looking for a new IP if it was just suspended. Computers will not check the validity of their IP until 50% at wich poing they will aske the DHCP server if it is still valid. So if you have an 8 day lease duration the computer will not check it's IP until day 4. I would start there. Dan,

I'm supporting users that travel from site to site - each site has a different subnet. Occaisonally when they log into a respective site, the IP address they obtain is still pointing to the last site they were at. Our network admin is a peach to work with and I'm not sure how things are set up. I know we use DHCP and the quick fix is just deleting/releasing that 'stuck' IP address. Is this a symptom of something that isn't configured properly in DHCP? We get multiple calls weekly to correct this. Thanks, Dan I’m curious if you can help me.
