PNRPsvc Failed To Start, HomeGroup and Peer Name Resolution service Problems

We recently con­fig­ured a cus­tom sys­tem for a client using Win­dows 7 Home Pre­mium. Every­thing was run­ning great until recently when our client said they were receiv­ing blue screen errors, and hav­ing net­work prob­lems. A quick review of the error logs showed that the prob­lems were all stem­ming from Peer Net­work­ing Ser­vice, PNRPsvc, and other depen­dent ser­vices and there fail­ure to start. After research­ing the issue we found that the prob­lem relates to a file named “idstore.sst”. This file is encrypted, and con­tains infor­ma­tion relat­ing to your Home­group, and Home­group set­tings. In our case, we believe an out dated ver­sion of Syman­tec cor­rupted the file while con­fig­u­ra­tions were being made.

So our solu­tion is as fol­lows. First we updated our anti-virus client, as well as con­fig­ured all related secu­rity ser­vices. We then deleted the fol­low­ing file…

C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\idstore.sst

You may need to show your hid­den files and fold­ers in order to nav­i­gate to this loca­tion. Once that was done we restarted the com­puter and again tried to con­fig­ure the Home­group. At this point our issue was resolved. We’re able to make changes in the Home­group con­fig­u­ra­tion, and our error log is clean, clear, and free of errors.

Let us know if this arti­cle was help­ful by leav­ing a com­ment below. Happy computing.

Setup failed while installing sub-component Exchange ActiveSync with error code 0xC0070643

In the process of set­ting up a new 2003 Exchange Server, we were con­fronted with the fol­low­ing error while installing Ser­vice Pack 2.

Setup failed while installing sub-component Exchange ActiveSync with error code 0xC0070643 (please con­sult the instal­la­toin logs for a detailed descrip­tion). You may can­cel the instal­la­tion or try the failed setup again.

Dig­ging into the instal­la­tion logs we see that the setup is fail­ing while attempt­ing to install MSXML:

[18:52:22] Call­ing MSXML installer with com­mand line: “msiexec /i msxml3.msi /q reboot=“ReallySuppress”“
[18:52:22] Process cre­ated … wait­ing (-1)
[18:52:23] Process has exited with 0x000643
[18:52:23] The command

msiexec /i msxml3.msi /q reboot=“ReallySuppress”

failed, return­ing error code 1603 (Fatal error dur­ing instal­la­tion.). — ID:31136 — ScCre­ateProcess (f:\tisp2\admin\src\libs\exsetup\hiddenw1.cxx:1821)
Error code 0XC0070643 (1603): Fatal error dur­ing installation.

The event logs sub­se­quently tells us:

Event Type: Error
Event Source: Msi­In­staller
Event ID: 1013
Descrip­tion:
Prod­uct: Microsoft XML Parser — Your sys­tem has newer ver­sion of MSXML3 SP5 than the ver­sion you are attempt­ing to install. Setup will quit.
