RPC Server Unavailable

Recently my Uncle tried to update his new(ish) computer from Windows XP SP2 to Windows XP SP3, but he kept receiving the following error:

RPC Server Unavailable
Service Pack 3 installation did not complete

If you happen to run into this error, the most likely cause is that you don’t have the EnableRSS subkey in your registry. Naturally the first step is verifying this.

Click Start, click Run, type regedit, press Enter.

Locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

If the EnableRSS registry entry does not exist, create it.
– Click the Edit menu, point to New, and then click DWORD Value.
In the New Value #1 box, type EnableRSS, and then press ENTER.
Right-click EnableRSS, and then click Modify.
In the Value data box, type 0 (zero), and then click OK.

Exit Registry Editor.

Now retry the Service Pack 3 installtation.
