Error 0xc00d0403 Forefront TMG 2010. How to fix?

Question

Microsoft

The Forefront TMG Configuration Agent was unable to update the local registry with changes made in the central store.
The failure occurred due to an error: 0xc00d0403
Good afternoon. Clean Win server 2008 R2. Pure TMG 2010 + SP1 + Rollup1 + SP2 + Rollup2 (I'll put 3.4 a little later) But they don't seem to matter.
Yes, and it's surprising that I don't see anything special in the search, except for advice to install service packs.
The error began with the basic installation, but was not corrected with each update.

Answer 1

It seems that the reason is clear - there are no full rights to the folder in the program files, but it's strange - I add full rights, writes to the storage, everything is fine, but after a while access disappears altogether, I go to look at the rights to the folder - and there my account is completely cut out)
In general, TMG lives his own life .. I’m already thinking if it’s because he’s on a virtual machine ..
