This article is dedicated to those who are unable to configure IIS on Windows XP (SP2) and frequently encounter this error message whenever they try installing IIS,
Error message: Setup cannot copy the file staxmem.dll. Please insert the "Windows XP Professional Service Pack 2 CD".
Don' worry, i got bogged down with this, until recently, i found out cause and solution of this problem..
Cause:
It happens when the secedit.sdb database file in your pc gets corrupted,
Solution:
1.Click Start, click Run, type cmd, and then click OK.
2.Type in :
esentutl /p %windir%\security\database\secedit.sdb
This will repair the database file.
3. Try to install IIS again...believe me it works and IIS gets installed quickly !!!
