Windows resolver question...

[Abello, Vinny]

Although this isn't a BIND question but rather a Windows client question,
I'll give you the quick answer anyway because this drove me nuts when I went
to Vista. Windows Vista and Windows 7 handles unqualified multi-label name
queries differently. If you have a period in any part of a hostname, Windows
Vista/7 will not append the domain suffix by default during resolution. You
can change this behavior by modifying the Local (or network) group policy
setting:

Computer Configuration\Administrative Templates\Network\DNS Client\Allow DNS
Suffix Appending to Unqualified Multi-Lavel Name Queries

Set that to Enabled and you should get the old behavior.

I know it's not strictly related to bind, but Google has failed me...
I'm hoping to find some expertise (or at least a pointer,) here. :)

I work in an environment where most desktops live in the corp.x.com 
domain, and I manage 2 other subdomains of x.com ).

I'm not positive, but I could swear when I was running Windows XP, that 
I could ping, telnet, ssh, vnc, etc. to abc.sub from my desktop in 
corp.x.com without any trouble at all.

Now I have Windows7, and nothing works without the fully qualified 
domain name. I have the (risky) checkbox checked to "Append parent 
suffixes of the primary DNS suffix," just like I did in WinXP.

What's different in Win7?

Given the split nature of the x.com domain, I'm wondering if Win7 might 
be keying off the '.' in abc.sub, and going to the root servers on it's own?

If this might be the case, Is there a way to modify this behavior? 
Anyone know the Windows equivalent of setting ndots to 2?
