Symptoms
MSDNS is used as the DNS server. Every time you try to update domain hosting settings or DNS settings, Parallels Plesk Panel stalls. Sometimes, it may fail with the following error:
Failed domain creation: Unable to update domain data: Unable to create dnsmng object: dnsmng failed: Empty error message from utility
The following message can be found in the event viewer:
Faulting application DNSMng.exe, version 9.501.0.0, time stamp 0x4bc1f9fd, faulting module MsProv.dll, version 9.501.0.0, time stamp 0x4bc205bc, exception code 0xc0000005, fault offset 0x000600bb, process id 0x56c, application start time 0x01cae1ae46c559db
The utility “%plesk_bin%\dnsmng.exe” cannot be run from the command line. It fails with the error:
DNSMng.exe – Application Error : The instruction at “0x00ba74ac” referenced memory at “0x00bd2108″. The memory could not be “read”
Resolution
The issue is caused by the installation of MS update KB976576. This update updates libraries that are used by MSDNS.
