Kerberos Configuration Manager for SQL Server: Access of system information failed!

Question

I'm trying to use the new Kerberos Configuration Manager for SQL Server tool that was released recently to verify SPN on several SQL Servers, but any time I attempt to connect to a server I get the following error in the log:
6/24/2013 3:48:22 PM Info: Connect to WMI, \\<HOSTNAME>\root\cimv2
6/24/2013 3:48:25 PM Error: Access of system information failed System.DirectoryServices.AccountManagement.PrincipalOperationException: An error (1332) occurred while enumerating the group membership.  The member's SID could not be resolved.
   at System.DirectoryServices.AccountManagement.SAMMembersSet.IsLocalMember(Byte[] sid)
   at System.DirectoryServices.AccountManagement.SAMMembersSet.MoveNextLocal()
   at System.DirectoryServices.AccountManagement.SAMMembersSet.MoveNext()
   at System.DirectoryServices.AccountManagement.FindResultEnumerator`1.MoveNext()
   at System.Linq.Enumerable.Contains[TSource](IEnumerable`1 source, TSource value, IEqualityComparer`1 comparer)
   at KerberosCM.WMIHelper.isUserLocalAdmin(SystemInfo si, UserPrincipal user)
   at KerberosCM.WMIHelper.getUserInfo(SystemInfo mi)
6/24/2013 3:48:25 PM Error: Error System.Exception: Access of system information failed!

   at KerberosCM.SystemInfo.GetInfo()
   at KerberosConfigMgr.Utility.Login(String serverName, String login, String password, Boolean isCmdLine, Form uiForm)
Things I have tried to resolve this:
1. Verified that my account is a Domain Admin.
2. Attempt to connect locally without inputting any information for server/user/pw
3. Attempt to connect remotely using server/user/pw
I always receive the same error message and log: Access of system information failed!
Has anyone else run into this issue?

Update to this:
There were some invalid user accounts added to the Local Administrators group only showing up as a GUID. This caused the enumeration of the group to fail and generate the error in my original post. Removing those user accounts from the Administrators group
got past the enumeration error.
However, now when attempting to connect to the servers (locally or remotely) I get this error:
6/27/2013 10:24:24 AM Info: Connect to WMI, \root\cimv2
6/27/2013 10:24:38 AM Error: Access of system information failed System.Runtime.InteropServices.COMException (0x80070035): The network path was not found.
