Setup was unable to open information file

I had SP3 installed on my PC. But there was no SP3 CD. So had some trouble installing IIS and other win components. So I obtained a SP3 EXE. It took half an hour to install, but it installed without errors.

When I went to add/remove components to install IIS, I got the error:

Setup was unable to open information file fp40ext.inf

This was followed by some 'error 0x2'. Looked up on the net and found some good pointers.

fp40ext.inf is a FrontPage extension info file. It was missing from the C:\Windows\inf folder. I copied it to this folder from C:\ServicePackFiles\i386 folder. Then I got the error fp40ext.dll was not found. Copied this file too from ServicePackFiles to the c:\windows\system32 folder. Then I got the error about missing pinball*.inf file. Taking cue from a website, I opened the sysoc.inf file and commented the line for pinball, using ';' character. Also commented the line for msnmsn (the next error source).

After this, the add/remove component dialog box opened, I was able to install IIS (except for the file admxprox.dll which I got from Xp-SP2 CD) successfully.

Mambo guestbook unhacked

Found out that one of my Mambo website's guestbook (com_guestbook) was hacked. When clicked on the "Sign my guestbook" link, it would redirect to the URL - http://www.vur6un.somee.com, which was also a bad address!

I went through the Mambo database using phpMyAdmin and exported the whole db as an SQL file. Then searched the file for the above URL and found the culprit record in the mos_guestbook table which had the URL embedded in it.

When guestbook was being displayed the code in the bad record would get EXECUTED and cause the page to be redirected to the specified URL.

After deleting this record from the mos_guestbook table, the guestbook started functioning properly again.
