Ok, hello everyone.. I have a very strange problem. Here are the details: Remote location in Corpus Christi connecting via frame relay to servers in Houma, LA. Corpus location has a 2620 Cisco with internal CSU/DSU. Here in Houma we have a 3620 with an external Adtran TSU, both routers are routing ospf. We have an pop3 server here in Houma that all of our remote locations connect to. Corpus is the only location that can't send Microsoft attachments, sometimes it works, sometimes it don't. They seem to be able to send any other type of file that isn't an .xls, .doc, or .mdb. They can zip up their microsoft attachments and send them. Here is what I have isolated so far:
1. Not their workstations, they can take a laptop to another location connected via frame and send attachments all day. Once they get back to Corpus, they have the problem again.
2. Not the server, we have about 250 people connecting to the same domain on the server and can send any type of email attachments.
3. There is no size limit on attachments for anyone, including the users in Corpus.
4. No router configuration anomonlies, on either side.
5. Virus? Don't think so, why would they be able to take the same pc somewhere else and have it work?
I'm totally stumped. Called Cisco, they said it isn't the routers. Called MCI, they say it isn't the circuit. I KNOW it isn't the pc's, or the server. We do have a PIX firewall, but that shouldn'g come into play on anything within our internal network, and I have checked the configuration anyway. Any entries that correspond to that particular location are no different than any of the other locations. What in the heck could cause this!!!
Thanks for you help,
