Exchange 5.5 not allowing attachments !

[MadGutts]

I have an NT4 box running exchange 5.5

A few weeks ago the server stopped all e-mail services. The server was reset and all the email came back. Now for the last 3 weeks, all users cannot get attachments on the email!

The clents are running Outlook 2000. I have created a new user which cannot recieve attachments. Also the server seems to be running very slowly and task manager reports 100% of useage.

Help !

Has anybody seen or heard of this before?

Thanks in advance
