Hello, about 2 weeks ago all my exchange services and IIS services ended with event ID 7031, it happened two or 3 times. I made sure I had all MS patches for windows and exchange, including the SP3 roll up. The services are not ending anymore but atleast once a day my clients are having very slow connectivity to the exchange info store, outlook throws the trying to retreive info from the exchange server message. The SMTP queue is completely normal. I noticed the activity light on my router is constantly blinking at a fast pace. When Ive seen this before it was from a DOS attack like sql slammer, only much worse. I setup a packet monitor on the server and all traffic looks normal. Mainly TCP and some FTP data. If I unplug the server from the network, the traffic goes to normal. Is there something I could have missed on the patch side. Does anyone have any other troubleshooting ideas? I appreciate any replies. Thank you.
