[Samba] Samba 3.5.6 with Win7 failure (XP works)

[Jeff Blaine]

Hi all,

We're testing 3.5.6 as an upgrade to our old 3.0.x instance.

Our XP boxes can see our Samba 3.5.6 shares fine.

Our Win7 boxes cannot.

    "The specified network name is no longer available."

Relevant config portion is as follows:

    log level = 20
    workgroup = OURCOMP
    security = ads
    encrypt passwords = yes
    realm = OURCOMP.ORG
    password server = DC1.OURCOMP.ORG
    client signing = mandatory

I've also tried "client signing = auto" to no avail.

Thanks for ANY advice!
