PHP errors in IMP/Horde (Only when using IE6)

[RiXarD]

I think I've encountered one of the strangest and unexplainable error I ever had to solve.

What is the problem:
Since a couple of days some people receive the following error when they try to login to IMP/Horde (i.e. http://webmail.domain.com) on my Win Plesk 7.6 server:

PHP Warning: Unknown(): Unable to load dynamic library 'C:\Program Files\SWsoft\Plesk\Additional\Php4\extensions\php_mysql.dll' - The specified module could not be found.in Unknown on line 0

PHP Warning: Unknown(): Unable to load dynamic library 'C:\Program Files\SWsoft\Plesk\Additional\Php4\extensions\php_xsl.dll' - The specified module could not be found. in Unknown on line 0

This error is on every page (in every frame) within Horde. It clearly is an server-side error, since the error is a PHP warning. People using Firefox or IE7 however, do not receive this error! Is that strange or what? Why do people receive a serverside error, when using a specific browser?

What have I tried:
Using Windows XP

The only explanation is that IMP includes browser specific files after detecting the user is using IE6, but why would that be? I can imagine this would be the case with css of js files, but other dll's on the server is totally unnessasery.

Can anyone explain me what is happening and how I can fix this error?

Reason for edit: some typo's

Solution ?

I have to dig deep (it was more than a year ago), but I keep of log on every server with important changes. Around this date I have done 2 things:

20-09-2007:
- php_mysql.dll en php_xsl.dll copied to system32
- System reboot

27-09-2007:
- php_mysql.dll and php_xsl.dll commented in php.ini in the Horde directory. This was the solutions for the errors with errormessages in IMP/Horde.

I Hope this helps you out. Please reply here if you solved it with this information.
