I did not notice the other post by you until I posted my first reply to you. No, there are no time based rules on the FW. We all have a tendency to work strange hours, and all I care is that the work gets done, not what time you are working on it. If you want to do e-mail at 2 AM or finish that proposal for a client then, it is fine, just show up for work when you should <g>. (The grin is for the reason that we are a bit lax on that as well, so long as you get you time in for the week and are making us money..)

DNS does not seem to be the problem. While the issue is affecting VPN and Outlook connections, it does not affect other remote connections and I am able to remote into any server I please using the FQDN. I do believe that pretty much rules out DNS issues and bandwidth issues at the router.

The DCDIAG results are kind of a red herring, but I would like ot get an answer to that issue, if it is an issue, since I do get the same results with or without the problem.

Right now AI am in sort of a hold pattern waiting for the problem to occur again, at which time I m going to up the logging since I do not see anything in the logs indicating a problem. I am also going to run NETDIAG as well to see what may come up.

I have placed our backup router in place, but the problem continues. One will not be able to log in form an external machine for hours or days ,then BAM!, it is fixed all on its own.
