Imported users cant access 2008R2 share via CNAME from Win8
Posted on 2013-01-28
We are currently testing Win8 and have an issue where some users cant access a particular 2008R2 file server. But only when trying to use a CNAME record. (from logon script or win explorer)
These same users are fine running Win7-64/XP-32/Vista. All CNAMEs resolve ok from win8 when using Ping.
Servers: FILE Win2008R2 bwjobs.domain as CName for Server04.domain (built 2011)
MAIL win2008R2 bwmail.domain as CName for Server01.domain (built 2010)
Client: Win8 Pro.
1. So when an 'old' user (ie me) log's on to the domain, the drive mapping fails for shares on bwjobs. When a 'new' user (someone created since the the system was installed 2yrs ago), log's on, all mapping works as currently for XP/Win7 users. I believe the 'old' users were imported into a new AD forest for the new 2008R2 domain, from an SBS2003 domain. Not migrated.
2. File server access is different....
2.1 For my logon, From explorer, \\bwjobs (the cname) throws a logon dialog. And wont accept credentials.
2.2 yet typing \\server01 (the real name) shows me the available shares as expected.
2.3. Yet \\bwmail (cname) shows me the std shares for an Exchange server. (from Win8)
4. I cant see how how the user's AD properties are different. (at least through the UI)
Any ideas on how to check the user properties and how the server properties for shares may be different ? (Note mapping in Win7 works for all users and servers)
The servers both have DisableStrictNameChecking = 1 in Lanman params, DisableLoopbackCheck not set in either, and no items in BackConnectionHostNames. (both running production so restarts are problemattic with backup windows)
