keep losing domain membership

[scinerd]

I have setup a few samba file servers and joined them to my windows domain. After a few days I try to connect to the machine and it errors saying there is no trust relationship.

I log onto the linux/unix server and do "net join mydom -U me" and everything goes back to working again. I have searched around but I can't find any thing about this or I'm just not using the right keywords. Anyone have any ideas? I have a very default setup the only thing really different is I'm using domain security.

thanks

Moved to the Networking forum where hopefully one of our Samba specialists can help.
