Hi!

I have upgraded my servers yesterday to CentOS 5.6 via yum update. Everything went smoothly except that i have client workstations not part of the domain that are not able to access the samba server anymore. The samba server is part of the domain. We recently added Windows 2008 R2 DC. Everything was working smoothly until the CentOS update.

I had a Win7 Workstation that i had success connecting when using the "net use" command:

net use g: \sambaserver\share /user:domain\username

The mapping worked right away and didn't even asked for the password. Normally, before the CentOS upgrade, i'd put \sambaserver in the UNC line of the Windows Explorer and i'd get a box asking for credentials. Entering "domain\username" as user and giving the password in the password line was working. Not anymore.

I have another XP workstation on another subnet (router wide open) and the mapping with the command line as specified above doesn't even work. For this subnet, i have to use the IP address because the workstations on it use a DNS which isn't aware or active directory (and cannot change this).

samba-3.0.33-3.29.el5_6.2 samba-common-3.0.33-3.29.el5_6.2
