I've just changed my ip scheme from a class A to a class C, (10.0.0.x to 192.168.1.1).

Most of my clients are experiencing an increase in the amount of time it takes to log in. Use to be instant now it takes up to 3-4 minutes.

What would causethis slow down?

The slow down is only when logging in, the "loading your personal settings" and "applying your personal settings" screen is up for about 3-4 minutes before the desktop appears.

No slow down appears once they are logged in.

I'm unable to know 100% sure what the issue is, same users on same computer before I changed the IP address.

Make sure you have proper net masks assigned for your new network. Remove the unneeded old network statements. Make sure your DNS/WINS/hosts file is correct. Make sure your default route is correct.

(NOT AN ANSWER, JUST QUESTIONS) Are your users logging in with Terminal Services? Are they assigned IP's via DHCP or Manually? What OS are you using?

Is this a windows 2000/XP environment? What server OS are you using? Are you using WINS or DNS?

Once I get some more info I may be able to help!

This happened when we were moving from a classC to classB with a different schema. In short, dump your dhcp database. Also we found that flushing the arp cache on our switches and routers helped speed things along too.
