| Description | Unable to parse the delivery route anlsf.msbp.co. Since errors in delivery routing parameters can result in misrouted mail, the Internet Mail Service will not start until this error is corrected. |
| Event Information | According to Microsoft: CAUSE: The Imcadmin.dll file corrupts the heap when there are too many entries in the table. RESOLUTION: The new Imcadmin.dll file only prevents the problem from reoccurring. You still need to perform the following steps to resolve the situation that is currently occurring: 1. Run IMCCOPY (from the Exchange 5.5 Server CD \server\support\utils\i386) to copy out the information. Command line: IMCCOPY -save routes c:\exchsrvr\imcdata\save.txt 2. Open Save.txt. 3. Look for the [Routes] section. It should look similar to the following: [Routes] DeliveryRouting=+ +DOMAIN.COM;xxx.xxx.xxx.xxx;0 DefaultRouting= 4. Delete everything after DeliveryRouting= and before DefaultRouting=.The updated list should look like: [Routes] DeliveryRouting= DefaultRouting= 5. Save the updated file to save_fix.txt. 6. Run IMCCOPY again to restore. Command line: IMCCOPY -restore routes c:\exchsrvr\imcdata\save_fix.txt 7. Start the Internet Mail Service and verify that it starts. 8. Run ADMIN to verify routes are gone. 9. Next, either re-enter the routes manually via ADMIN or "restore" the routes using IMCCOPY. Edit the save_fix.txt file and add the routes using the [Routes] above as a guide. Then use the following command line: IMCCOPY -restore routes c:\exchsrvr\imcdata\save.txt 10. Restart the Internet Mail Service. |
