Thank you Fabrice,
that's interesing.  I am just wondering if `eshell-extended-glob' gets 
confused with the Windows path, i mean, the disk name 'c:' in front.

Could you check if the following works?
M-x eshell RET
cd "c:/tmp"
ls -l dir*/*.txt

I am also curious if:
M-: (equal temporary-file-directory "c:/tmp/") RET
=> t

Thank you,
Tino
