We are running SCCM 2012 R@ on Server 2012 R2. We have a site server with multiple site system servers running the MP/DP roles. Initially all MP/DP services were successfully running in https mode. Everything worked as expected. In an effort to improve imaging performance, we changed the DP role from https to http and all works as expected except the Multicast service immediately began reporting unable to connect errors.

The errors were 403 forbidden, and what I should have done (I think) is simply remove the SSL requirement on the MCS service in IIS. However, what I did do was disable (uncheck) Multicast in the DP properties. Now when I check it again to re-install, I get a continuous loop of failed installs. The mcssetup.log simply reports that mcs.msi failed to install with a 1603.

I've tried numerous combinations of rebooting, re-installing, etc, with no results.

Obviously we have all the prerequisites as we initially installed the system and it was functional.

I really am trying to avoid complete removal/reinstall of PXE/WDS in order to get MCS re-installed.

One remaining clue I have is that on a functioning system, IIS contains and SMS_MCS and SMS_MCS_AltAuth site. On the troubled system, after successful uninstallation of the multicast service, the SMS_MCS_AltAuth site remains. I'm curious if this could be getting in the way of the install but am nervous at this point about making additional changes.

Any suggestions for additional troubleshooting?

The 1603 is a generic MSI error.

Can you please share the mcs.msi log file?

How much of it would you like? It's almost 2M of text, mostly listing the msi properties as far as I can tell. The meat of it seems to just be a repeat of the 1603.

Can you please put the log file in OneDrive that we can access?

I believe this should get you there.

The problem is that the MCS setup could not configure IIS. The MCS setup wanted to create an app pool for itself, but that failed. It looks like the app pool already exists. This will happen if the MCS role did not successfully complete a deinstallation.

Try removing the removing the app pool "SCCM Multicast Service Point Pool" from IIS, and see if the MCS setup will succeed.
