Active directory adsiedit.exe lists account times as a long integer number. To convert, use the following.

This is an old problem when Vista first came out. The problem was with Samba not using NTLMv2, which is seems to handle now (2010-6-8).
http://www.jimmah.com/vista/Networking/ntlm.aspx
When accessing a file share on a remote computer or device, Windows Vista will refuse to send your password using older encryption methods.
Unfortunately, many NAS devices as well as older versions of linux do not understand the newer encryption methods. This keeps you from being able to access these devices.
The solution is to force Windows Vista to use the older encryption methods. To do that, follow these steps:

…For example, backing up your Documents (Vista) or My Documents (XP) folder to a USB thumb drive is as easy as typing a variation of either of the following lines:
xcopy C:\Users\username\Documents g:\backup /D /E /C /R /H /I /K /Y xcopy "C:\Documents and Settings\username\My Documents" g:\backup /D /E /C /R /H /I /K
(Swap out “username” with your ID, and don't forget to put the quotes around the file path in XP.)
These examples assume you're using the default location of the folders. Change the drive letter to match that of your USB drive, or whatever device you're backing up the file to. At the end of each command are several switches:
The /D switch ensures that the files being copied are newer than the ones already on the destination device. The /E switch will copy empty directories and subdirectories. The /C switch ignores errors. The /R switch copies over read-only files. The /H switch copies hidden (system) files. The /I switch creates directories on the destination device automatically. The /K switch includes attributes to avoid making all the copied files read-only. Lastly, the /Y switch gets rid of the prompts when overwriting files.

It’s kind of ironic, but as hard as Microsoft has been pushing IPv6 adoption, Windows does not fully support IPv6 in all the ways you might expect. For example, in Windows, it is possible to include an IP address within a Universal Naming Convention (\\127.0.0.1\C$, for example). However, you can’t do this with IPv6 addresses because when Windows sees a colon, it assumes you’re referencing a drive letter.
To work around this issue, Microsoft has established a special domain for IPv6 address translation. If you want to include an IPv6 address within a Universal Naming Convention, you must replace the colons with dashes and append .ipv6.literal.net to the end of the address — for example, FE80-AB00–200D-617B.ipv6.literal.net.
