DHCP database and Jet errors caused by AVG 9

December 3rd, 2009. Published under Uncategorized. No Comments.

Suddenly my Windows Server 2003 AD controller was throwing errors about the DHCP Server service running on it and the Jet database.  The Event IDs were 485, 215, 1014, 1016, and 1010.  Here are the specific errors logged:

* Event Time: 23 Nov 2009 01:31:41 AM
* Source: ESENT
* Event Log: Application
* Type: Error Event
* Event ID: 485
* tcpsvcs (3800) An attempt to delete the file “C:\WINDOWS\System32\dhcp\j500322E.log” failed with system error 5 (0x00000005): “Access is denied. “.  The delete file operation will fail with error -1032 (0xfffffbf8).

The following problem occurred with the Jet database -1032:

Jet database read or write operations failed. If the computer
or database has just been upgraded, then this message can be
safely ignored. If this message appears frequently, either there
is not enough disk space to complete the operation or the database
or backup database may be corrupt.  To correct this problem,
either free additional space on your hard disk or restore the
database. After you restore the database, ensure that conflict
detection is enabled in DHCP server properties. For information
about restoring the database, see Help and Support Center.

Additional Debug Information: JetBackup.

These were driving me nuts.   I tried a few things like copying over the DHCP configuration files from my other AD controller (which was configured with DHCP Server but disabled for backup purposes), but nothing I did worked.

Then I realized the day before these errors began I upgraded the AVG client software from AVG Antivirus Network Edition 8.5 to AVG Antivirus Business Edition 9.0.  So I Googled about these errors and threw “AVG” into the search and found this forum thread, which supported my theory of the AVG upgrade being the culprit.

I then contacted AVG Technical Support about the issue, and the response I received instructed me to “remove the AVG Service for optimizing scans”.  The specific instruction was to run command line switches on the installation package.  So using a recent installation package, I typed the following from a command line:

avg_ipw_stf_all_90_707a1765.exe /REMOVE_FEATURE
fea_AVG_NtfsChangeJournalCach

A wizard dialog will appear where I selected (per instruction) “Add or remove components”, and just clicked “Next” through the wizard.  Do not modify the component selection.  The instructions also said to restart the server after this wizard, which I did NOT, and the issue still was resolved even though I have not restarted.
