We have been using Samba To connect 2 NT4 PC's to our Unix boxes. These Unix boxes use veritas clustering software for failover. During our failover test the veritas software unmounted the filesystems and moveed them to another server. We are connecting the PC's to the servers using a virtual IP address controlled by veritas. So when the second box mounted and the application on the PC tried to write out to the file we thought that it would reconnect. However, the PC's would not reconnect at all. Everything in Samba is configured properly and I can swap out those PC's with different ones and everything works correctly. So here is my question. Is there something like a lock file or a configuration file in NT that will not let these PC's reconnect using there net application? It has to be something PC related, but it is weird that both of these PC's were working great and then we pulled the rug out from under them and they would not reconnect. Any help would be appreciated. Brian Anderson
