Hi. I have CentOS 6 on a HP ProLiant ML110 G7. We have a cobol invoicing system that prints to LPD printers on Windows hosts via CUPS. All works great until the ADSL service goes down. The printers stop working and the service restart gives a connection error. What will be happening here and how I can solve it? Our previous server was on CentOS 5 and worked OK. Thanks. -- Juan Pablo De Mola Rodr?guez

I have tested restarting networking, re enabling printers, restartig the service. The only way to print is sending release commands from the CUPS web interface. The telnet login screen also become slow when the Internet goes down.

Are the name servers for your network on the "other end" of the ADSL connection? If so, you might be able to resolve some of the issues by editing the hosts file to make sure the local systems are resolving even when the name servers are unavailable or running a local caching nameserver.
