Greetings --
While the Blaster Worm is by far and away the most common cause of
RPC errors, there can be cases when its not the worm that causes the
problems. Additionally, the Microsoft patch does not remove the
worm, nor is it intended to do so. It is designed to block the
vulnerability that lets the worm into your PC in the first place, and
to prevent reinfection.
In this case, more troubleshooting is indicated. Can the PC be
booted into Safe Mode? Here are a couple of things to try, in
addition to the tools listed in my first post:

System File Checker
System File Checker (sfc.exe) is a command line utility that scans and
verifies the versions of all protected system files after you restart
your computer. If System File Checker discovers that a protected file
has been overwritten, it retrieves the correct version of the file
from the %systemroot%\system32\dllcache folder, and then replaces the
incorrect file.
Syntax:
sfc [/scannow] [/scanonce] [/scanboot] [/cancel] [/quiet] [/enable]
[/purgecache] [/cachesize=x]
Parameters:
/scannow
Scans all protected system files immediately.
/scanonce
Scans all protected system files once.
/scanboot
Scans all protected system files every time the computer is restarted.
/cancel
Cancels all pending scans of protected system files.
/quiet
Replaces all incorrect file versions without prompting the user.
/enable
Returns Windows File Protection to default operation, prompting the
user to restore protected system files when files with incorrect
versions are detected.
/purgecache
Purges the Windows File Protection file cache and scans all protected
system files immediately.
/cachesize=x
Sets the size, in MB, of the Windows File Protection file cache.
If the above doesn't help, you may need to perform a repair
(a.k.a. in-place upgrade) installation:
