I have a 5510 at the main site, and a 5505 running 8.2(5) at the remote site. I have an issue where it looses connection to all of the internal servers at the main site, and the only way to get it working again is to do a ipconfig /renew on the machine. It happens to all of the machines on that site, just at random times. There are times where computers boot up and the login script does not run. How do I fix this?
