Sorry for the late posting. I had it ready to go but was sidetracked by some other things I had to do first.
Thank you to Jon Barrett who pointed out that yes, you can write to a server with a volume formated as NTFS from a Linux client. I should have checked first before guessing that it might not be possible. Especially since I could actually login into one of our NT servers and find out.
Logging in to a one of our NT servers is remarkably similar to that in Windows. In Xandros Desktop Business Edition version 2.5, click on the File Manager icon --> Tools --> Mount Network Share.
Type in the address (we use something like \\xx.xxx.xxx.xxx\fo) and, once past the username and password, I was able to read and write files to the NTFS partition mounted there. Now if only I could do that with my own hard drive. Sigh.
Thanks again Jon!
