Cryptographic service fails to start

[Guest]

A machine running XP Home fails to start the cryptographic service. When
attempting to start from the services menu it responds with error 2: the file
specified cannot be found.

I am unable to identify which file it is referring to however I have run
through various procedures from articles found in the discussion forums,a on
the ms web site and including www.updatexp.com/cryptographic-services.html.

Due to cryptographic services failing to start no update will install.

After a bit of a brainstorm I decided to check thru the registry entires and
discovered some missing elements. If you have the same problem check your
registry HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\CryptSvc\Parameters

You should have entries for:
default REG_SZ (value not set)
ServiceDll REG_EXPAND_SZ %SystemRoot%\System32\cryptsvc.dll
ServiceMain REG_SZ CryptServiceMain

Although all the files were present and the services registered because
these parameters were missing the service file to start was not defined.
