Windows 7: Unable to create homegroup/ allow device access (advanced media share)

Windows 7 Ultimate x64
Unable to create homegroup/ allow device access (advanced media share)

Hi there,

I have been troubleshooting this problem for some time and have run out of ideas. I will try to describe the issue and steps I've taken to resolve it in full detail.

Just over a week ago I noticed my PS3 was no longer seeing my laptop as a media server. I then noticed that the wireless tray icon just showed a red x. Eventually I ran an antivirus scan and it seems a tracking cookie was the culprit. Once the infection was removed this problem was resolved.

Great, so I thought. I then discovered I was unable to turn on media streaming. When I clicked on it, it just showed as processing then nothing would happen. Eventually I ran a rootkit scan and discovered a MSS problem which I happily removed.

I could then turn it on. Great! So I thought. Now when I access the list of devices they simply remain blocked and I can't allow them access.

I can't create a homegroup either. When I try to do so I am informed that I must be on a home network to do so yet I am clearly on a home network (At some point earlier I had deleted the the existing homegroup.

I have tried a number of steps to resolve this:

Disabled all firewalls; unistalled antivirus; restarted all appropriate services (UPnP, Windows Media Player Sharing etc); disabled all non-microsoft services on startup; Checked IPV6 settings; removed network profile and created from scratch, reinstalled WMP, ran Microsoft Fix It, checked the PS3 and laptop have same SSID and are on the same subnet, rebooted router, tried using 3rd party media servers (Playstation Media Server, XBMC), I disabled the virtualbox adapter, all other adapters in fact. I think that's about it, I may have forgotten something. I can't try a system restore as unfortunately there is no restore point before the issue raised it's ugly head. When I run the homegroup troubleshooter it says the problem is network related but the network troubleshooter dosn't find any problems.

Interestingly the PS3 recognizes XBMC but when I try to add files to the library to share they don't appear on the PS3.

I have established there is connectivity as I'm able to ping the PS3 and it appears under the list of devices all of which remain blocked. My flatmate CAN access my shared media from his PC.

I suspect these problem are related to the original infection, as I've removed it though, or at least appear to have removed it, I'm pretty stumped now.

Any suggestions would be much appreciated.
