Problem with sitepreview

[Sunyl7]

We've plesk windows 9.5.5 installed on windows 2008 64bit machine, all of sudden all accounts site preview shows 404 error with message description as -

-------------------
HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

Module IIS Web Core
Notification MapRequestHandler
Handler StaticFile
Error Code 0x80070002
Requested URL http://11.22.33.44:80/sitepreview/sitepreview.dll?domaintest.com/
Physical Path C:\inetpub\vhosts\webmail\horde\sitepreview\sitepreview.dll
Logon Method Anonymous
Logon User Anonymous
-------------------

Don't know why it is picking up the physical path as C:\inetpub\vhosts\webmail\horde\sitepreview\sitepreview.dll in IIS settings I can see sitepreview dll file proper in ISAPI files also in site advanced setting the physical path is proper C:\inetpub\vhosts\domaintest.com\httpdocs with app pool set to plesk default 2.0 pool

Any help would be appreciated.

Thanks
