SBS Admin account can't access shares

Thanks ormerodrutter.

The Administrator group, of which the admin account was a member, was still present in ACL. I've added the Admin account by name to ACL and all now seems to be well, but I'm a bit baffled as to why the problem arose in the first place.

I've just created a new Security Group using the SBS console. I specify that the group should be able to receive email and then get an error:

Add a New Group Failed
Unable to create an e-mail address for this group

The new Security Group does not show up in the SBS console, but it does show up in Active Directory Users and Computers.

If I go to the Exchange Management Console and try to create a Distribution Group for the new Security Group there, then I get the error:

Error:
Active Directory operation failed on SERVERNAME.domainname.local. This error is not retriable. Additional information: insufficient access rights to perform the operation.
Active directory response: 00002098. SecErr: DSID-03150E8A, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

The user has insufficient access rights.

Exchange management shell command attempted:
Enable-DistributionGroup –Identity ‘domainname.local/MyBusiness/Security Groups/Group-Name’ –Alias ‘GroupName’

Elapsed Time: 00:00:00

I think there’s stuff on the web about similar errors with Exchange 2010, so I’m going to have a look at those pages and see if there’s anything to be done.

The account I’m using is the admin account I created when prompted by the SBS installation routine, so surely it should be a proper, paid-up member of the Administrators  security group?

I experienced similar problem in SBS2003 environment before, not exactly the same but the problem is related to Admin not having sufficient rights. Did you MOVE the Administrator account to a different OU?

If you are using the SBS Administrator account (the one preconfigured) and have such problem then there is something wrong in the system. If you are using an admin account that you have created then it must be something to do with permission not setup correctly. REmoving and recreating the account with a same name means they are different account.
