Amit,

I'm afraid you can't use easily the UID generated to your account by the 
SMB network domain controller, because it is too high. Traditionally Unix 
has that 16-bit limitation in the number of different users allowed in a 
system. As far as I know, only newer Unix-like (but not Unix) OSs have 
higher limits on UID numbers (Linux, QNX and such-like).

This is what I'd do assuming you have a machine-wide cygwin installation 
(not tested, no warranties this would work, you are welcome to be a 
willing guinea pig :-):

Create a local user in your box, not registered with the Domain Controler, 
that is, you login locally, no roaming profile, no network authorization.

Login to that account, open your cygwin shell to create the new home 
directory, log out. Login to your default account and edit /etc/passwd, 
change the home directory of the new account to the one of your real 
account. Close the shell. From the Windows Explorer, select the directory 
of your prefered account and assign shared ownership to the local account 
recursively. And, you may need to change access control from ntsec to ntea 
or not at all, and remove some custom ownership properties in the 
directories you want to access as well as playing a bit with chmod, see 
/usr/share/doc/cygwin-doc-1.3/html/cyg-ug-net/using-cygwinenv.html and 
filemodes.html for an explanation.
