Trying to view Public Folders in the Exchange System Manager can sometimes cause the error message “The SSL certificate name is incorrect – ID Number  c103b404” to occur. This happens when a SSL certificate on the default web server contains a different Fully Qualified Domain name (FQDN) than the internal server’s FQDN – externally the server had a different FQDN than what is used internally. If the Exchange System Manager thinks that the folder name is incorrect then it will not allow you to view the public folders.

One solution is to remove the SSL requirement from both the public virtual directory and the Exadmin in IIS. You should also read and review Microsoft Article ID : 324345. http://support.microsoft.com/kb/324345/en-us

Another solution is to use the ADSIEdit utility to manually stop the Exchange System Manager from using SSL. You can do so by doing the following:

1. Install the ADSIEdit Utility (a Windows Server Support tool) from your SBS CD using suptools.msi
2. Run a Microsoft Management console (Start->Run->MMC)
3. Open the ADSIedit.msc (browse to the Support Tools folder)
4. Drill down to: Configuration > Services >  Microsoft Exchange > Domain Name > Administrative Groups >     First Administrative Group > Servers > Servername > Protocols > HTTP > 1 > Exadmin
5. Right click msExchSecureBindings, and click Properties
6. Highlight :443: and click Remove
7. Click OK
8. Restart the Exchange System Attendant and the IIS Admin service

Another solution is to delete the certificate from the Default Web site properties and then re-running CEICW and re-apply the same certificate details. Then restart the IIS Admin Service and reopen the System Manager. You should now be able to access the Public Folders.

Alternatively you can check if you have the FQDN of the server on the certificate. You can also try adding the FQDN of the server and its IP address to the host file. Uncheck SSL in “ExAdmin” Virtual Directory based on KB, and restart ESM. If the issue still persists, uninstall the certificate temporarily from the default website folder and monitor the issue again, then reassign the certificate.

Still another way to resolve this issue is to remove the SSL on the Exadmin virtual directory. Follow the steps outlined below:

1. Click Start, point to Programs, click Administrative Tools, and then
   click Internet Services Manager.
2. Click your server, and then expand the Web site that contains the
   Exadmin virtual root (the default Web site is “Default Web Site”).
3. Right-click Exadmin, and then click Properties.
4. Click the Directory Security tab.
5. Under Secure Communications, click Edit.
6. Click to clear the Require secure channel (SSL) check box. If Require
   128-bit encryption is shaded, click to select Require secure channel (SSL), click to clear Require 128-bit encryption, and then click to clear the Require secure channel (SSL) check box again.
7. Click OK, OK.
8. Restart Exchange System Attendant Service (Services.msc) and then restart Exchange System Manager

If the issue persists then you can collect the IIS metabase on Exchange Server and send it to Microsoft support for further review.

1. On Exchange Server, install .NET Framework Version 1.1:
   http://www.microsoft.com/downloads/details.aspx?FamilyID=262d25e3-f589-4842-8157-034d1e7cf3a3&DisplayLang=en
2. Install MBExplorer by installing IIS 6 Resource Kit Tools:
   http://www.microsoft.com/downloads/details.aspx?FamilyId=56FC92EE-A71A-4C73-B628-ADE629C89499&displaylang=en
3. After installation is complete, access it from Start, Programs, IIS Resources, Metabase Explorer.
4. In the left pane, right click ”LM” to choose ”Export to file”, and then save it as IIS.mbk.
5. Compress the mbk file and send it to Microsoft for review.

Many times you will receive additional error messages along with the c103b404 error code. You might see something like the following when you use Exchange System Manager to view public folders in Exchange:
 
The SSL certificate server name is incorrect.
ID no: c103b404
Exchange System Manager

The connection was aborted. Ensure that the settings on your default Web site are correct and refresh the Public Folder Tree
ID no: c103b402
Exchange System Manager

The token supplied to the function is invalid.
ID no: 80090308
Exchange System Manager

I’ve already mentioned that the error can occur if you do not have the Fully Qualified Domain Name (FQDN) of the server on the Secure Sockets Layer (SSL) certificate. You can also get the error if an SSL certificate is incorrectly published to the Exadmin virtual root in Internet Information Services (IIS).

You can correct the issue by publishing a new SSL certificate that has the FQDN of the Exchange server to the IIS server.

You can also remove SSL from the Exadmin virtual root in IIS by following the steps mentioned previously.
