Here's my situation. I've got a router that's branched off of our central routing equipment. I have it split off because I have to have multiple PC's running at my desk, however there is only one ethernet line to my desk. My issue with this is that only one of my PC's can actually login at a high rate of speed while all the rest take at least 20 to 30 minutes to login. Local logins on these computers takes no time at all. It's only domain logins. I'm not sure if something got screwed up on the router, however nothing on it has been changed since it was orginially in place. I've tried different ports, cables, and computers with all the same results. Even my virtual machine takes forever to login to the domain even though it's on the computer that is running fine. I hope this makes sense because I've been trying to figure out this problem myself, but don't really know how you would google search this answer.
Your help is appreciated.
