I second the notion on the NIC. If you're using MB NICs, see if there's updated drivers, or put in a good Intel card or similar and try it again. BTDT.

Corrupt attachments again We ran into this where small attachments never had a problem. Start sending large attachments and it was reproducible. Ended up being a bad NIC at some level. Put a new NIC and the problem went away. Dell came out and swapped the system board and that fixed it permanently. From: Oliver Marshall [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 22, 2008 4:14 PM To: MS-Exchange Admin Issues Subject: HELP! Corrupt attachments again Hi chaps, We are still getting ongoing problems with attachments being corrupt. In a group of about 15 people we see maybe two or three a day that get corrupted. As I've said before, im 100% certain it's not exchange as I can't find a thing wrong, no error logs, no proof of corruption, no errors when running isinteg etc, and nothing NOTHING is reproducible. At the moment I'm sending two emails every 10 mins to a test account on the server, each email has two attachments (pdf and jpg). So far I've opened and viewed the same attachments 60 times and haven't found a thing wrong. My believe is that the attachments are getting corrupt before it hits their network. Their .co.uk name goes through an ISPs mail sevrer where it's filtering for spam and virus before being forward on. Their .COM goes through a full email-store-and-forward type filtering service with another provider. I've suggested that they get the ISPs to dump their mail in a pop box, and have the exchange box collect them from there. Once done, if a user has a problem, we can check the copy in the pop box and, if the attachment is corrupt there as well, we know it's not their server. If it isn't corrupt in the pop box, then, well, then I'm back to square one. Their connection is supplied by the serviced office company they lease from, but while it's very well used, it doesn't show any packet loss indicative of connections being dropped, so I'm inclined to rule this out. Has anyone got any other suggestions on how to bug hunt this ?
