If you get 8002801d register the asp.dll library

Today for the n-th time I got the 8002801d error on an asp page.
To fix that, usually (all the time I have seen it) you need to register again the asp.dll, as in the following example:

C:\> cd c:\WINDOWS\System32\Inetsrv
C:\WINDOWS\System32\Inetsrv> regsvr32 asp.dll

Hope this time I will not forget it anymore :)
