Recent changes in the company I work for "designated" me as the new IT guy at the office. I have no real formal training and the bulk of my knowledge comes from books and the times when I used to help our former IT person troubleshoot problems, so please bear with me.
Recently we've been losing external connection to our Windows 2003 server. It is our Domain Controller and is also running Exchange 2003. Our remote users use RPC over HTTP or OWA to access their emails. The symptoms start with a remote Outlook running rpc/http losing it's connection. Likewise OWA gives me an error. Also, I can't directly connect to the DC via remote desktop from outside the network but I can rpc over to a Win2k3 File Server from outside and from there successfully rdc over to the DC. I can't ping the DC externally but I can ping it internally. From the DC I can ping other devices on our network but nothing on the outside. A restart of the DC fixes the problem temporarily for approx. 24 hrs and the problem comes up again.
The latest episode happened at around 7:30am this morning.

Description:
DNS server has updated its own host (A) records. In order to ensure that its DS-integrated peer DNS servers are able to replicate with this server, an attempt was made to update them with the new records through dynamic update. An error was encountered during this update, the record data is the error code.
I'd appreciate it if anybody could point me as what the possible cause might be.
