When you install Exchange Server 5.5 Service Pack 4, you may receive the following error message:
System cannot find the file specified

Microsoft Windows NT ID No: 0xc0020002
You receive the error message when you update the Microsoft Outlook Web Access (OWA) component.

NOTE: You may also receive this error message if you manually remove OWA, and then try to reinstall it.


This issue can occur if you remove the Cmd.exe file from the %Systemroot%\System32 folder.


To resolve this issue, move the Cmd.exe file to the %Systemroot%\System32 folder, and then reapply Exchange Server 5.5 Service Pack 4.
