“Object Required” error while changing passwords using OWA

Posted by p_lider September 6th, 2010

After deploying MS Exchange 2003 server in your organization and configuring OWA to let users change their domain passwords you can face a strange issue. When users try to change their passwords, after clicking “OK” button they see an error message saying “Object Required” and their password are not being changed. This enigmatic error message means, that the MS Exchange cannot find a properly registered COM object in the registry. To solve the problem you must manually register the “iispwchg.dll” library on the MS Exchange server. The full command to do this is:

regsvr32 %windir%\system32\inetsrv\iisadmpwd\iispwchg.dll

The reason why MS Exchange does not register mentioned library by itself during the installation is unknown for me. However I noticed, that MS Exchange installers are written is such a way, so the administrators can demonstrate their knowledge and skills <ironic> before the MS Exchange product can start fully working.
