I'm unsure of the exact reason for this occurence, so I don't really know whether or not it relates to NT or to Microsoft Access. Occasionally, much more often than I'd like, one of the client machines will temporarily lose it's connection to the master .mdb file on the PDC. <br> We run, at the moment, a TCP/IP network that does not use DHCP. All addresses are static. Also temporarily, IPX/SPX is still used with the HP Jet Direct print servers on the network. All of the NIC's are Kingston 10/100.<br> The standardization of the NIC's, as well as the switch to TCP/IP were both done in an attempt to alleviate this problem. <br> The error itself is displayed within MS Access, and after closing MS Access out on the clients machine that encountered the problem, you can usually start it right back up. No reboot necessary, nor a logout then log back in. For some reason it seems that the connection is just dropped, and then can be restablished. There are apporximately 20 computers altering this and a host of other network database files constantly, and what really bothers me about the situation is the following.<br> About 30% of the time this occurs, the database file will need to be repaired. Anyone who's ever worked with Access will know that in order to repair the file, it cannot be in use. This results in me meandering about the office building asking people to please close out their database applications(keeping them out until it's repaired is actually the hardest part). If anyone has any suggestions, please post or just send me an e-mail. All responses will be appreciated. Thank you. <p>xtreme1<br><a href=mailto:rbio@excite.com>rbio@excite.com</a><br><a href= > </a><br>
