              - Microsoft Site Server version 3.0

            SYMPTOMS
            After applying Service Pack 3 for Microsoft Site Server 3.0 the 
            posting acceptor may fail when uploading files with the following 
            message in the browser: 
            
              No files were uploaded 
            
This is followed by a Error while uploading 
            contents dialog box with the following message: 
            
              The Web server returned the following 
              error: Unknown error was encountered 
This is 
            accompanied by errors in the event log on the Web server from source 
            CPSHOST. The first, with event number 8721, contains the following 
            message: 
            
              The file is empty or does not exist 
            
The second, with event number 8957, contains the 
            following message: 
            
              User: domain\user Unknown error was 
              encountered 
In addition, another error message 
            may display: 
            
              The Web server you selected does not 
              indicate support for the service provider you selected 
            
This problem may occur more frequently when 
            uploading larger files. 
            
            RESOLUTION
            A supported fix that corrects this problem is now available from 
            Microsoft, but it has not been fully regression tested and should be 
            applied only to systems experiencing this specific problem. If you 
            are not severely affected by this specific problem, Microsoft 
            recommends that you wait for the next Site Server service pack that 
            contains this fix.

            If an uninstall folder was created during the install of Site 
            Server 3.0 Service Pack 3 then you may restore the original posting 
            acceptor functionality by performing the following steps: 
            
              - Copy Cpshost.dll.32 from "\Microsoft Site Server\sp3\backup" 
              to "\Inetpub\Scripts"
 
 
- Rename the current Cpshost.dll in "\Inetpub\Scripts" to 
              Cpshost.sp3
 
 
- Rename Cpshost.dll.32 in "\Inetpub\Scripts" to 
              Cpshost.dll
 
 
            STATUS
            Microsoft has confirmed this to be a problem in Site Server 
            3.0.
