SYMPTOMS
Starting SNA Server Admin results in an Event ID 633 error stating:

The sharename COMCFG does not exist, or the SNA Server configuration file com.cfg does not exist.



CAUSE
This error may be the result of setting the NTFS permissions on Com.cfg to Admin Full Control only and on the directory CONFIG to Admin Full Control only. These permissions may have worked with Windows NT 3.51, but will fail under Windows NT 4.0. This problem may also occur with SNA Server versions 3.0 and 4.0 if the services are configured to run under the local system account.



RESOLUTION
Adding the group Everyone with Read access to the permissions will eliminate the error. The Com.cfg is located in \system\config directory. In addition, the COMCFG share also requires that the group Everyone have Read Access. For more information about how to eliminate the need for Everyone:Read access, click the following article number to view the article in the Microsoft Knowledge Base:

Note The Everyone group includes all users, even anonymous users and guests. Membership is controlled by the operating system. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
