ConfigMgr 1906 Hotfix KB4529905 [Out of band Hotfix]

A new hotfix KB4529905 for ConfigMgr 1906 has been released. This hotfix KB4529905 addresses the issue with delays in content distribution in Configuration Manager version 1906.

Just two days ago, I published about another hotfix KB4527297 for SCCM 1906. The hotfix addresses an issue where data sync between the Microsoft Store for Business and a SCCM site server will fail when a proxy server configured on the site.

As per Microsoft the hotfix KB4529905 fixes the below issue in ConfigMgr 1906.

The distribution manager (distmgr) component of the SMS Executive service does not process incoming package notifications (.PKN files) in a timely fashion. This can occur when there are multiple site control file changes, which in turn trigger distribution point checks. The main processing thread of distribution manager will show multiple entries resembling the following in the distmgr.log file“.

GetDPCRC - DP1.CONTOSO.COM
Finished GetDPCRC - DP1.CONTOSO.COM
...
GetDPCRC - DP2.CONTOSO.COM
Finished GetDPCRC - DP2.CONTOSO.COM

If you are facing delays in content distribution in your SCCM 1906 hierarchy and if you notice the exact same entries in your distmgr.log file, this hotfix is for you.

IMPORTANT – To apply this hotfix, you must have SCCM 1906 and KB4517869 installed. You don’t have to restart the computer after you apply this hotfix.

Microsoft releases these out-of-band updates to fix specific issues in the ConfigMgr version. You will not see these updates in the console unless you import them first.

The hotfix states it is only for the “site server”. Does it also apply to secondary site servers requiring a restore of the secondaries?
