V-79-57344-34004 - End of data set was unexpectedly encountered

Problem

We are using "Backup Exec 10D" with service pack4 from BUE. Currently trying to backup four physical servers, and one server always fails to to backup. Errors generated from the Backup Exec's job log:

Job log
Verify- \\Server\D: Unexpected end of backup set encountered on CERTANCE 1.
V-79-57344-34004 - End of data set was unexpectedly encountered.

Solution

Talked to other techs that use Backup Exec software and they were able to give me some tips for this error.

Fix1:
Force the NIC to the same speed of the switch it's connected to.
1. Go to Device manager by -> right clicking My Computer -> Manage
2. Select Device manager -> select NIC card -> right click NIC card
3. Advance TAB -> in the Property window select Speed & Duplex -> Change value drop down to forced speed, instead of "Auto"


Fix2:
1. Ensure the drivers you're using for the tape drives are compatible. This means if you have a tape library ensure the tape library drivers are manufactuers drivers. This is listed in your device manager as "Medium Changers."
2. Ensure the drivers for your "tape drives" are from Symantec Backup Exec. This is listed under your device manager as "Tape Drives."


The first fix1 solved my supposivly network issue.
