mDNSResponder repeating over and over in system log and other network issue

Hi all,

I wasn't sure whether to put this into printers or network, but as the printer is a networked printer and not a directly attached one, and my other problem is network related - figured it should go here.

First:

I'm having a problem with mDNSResponder - this is a sample of what's in my system.log file:

Sep 3 07:21:48 enterprise mDNSResponder[17]: Client application bug: DNSServiceResolve(Brother\032MFC-6490CW. printer.tcp.local.) active for over two minutes. This places considerable burden on the network.
Sep 3 07:27:54 enterprise mDNSResponder[17]: Client application bug: DNSServiceResolve(Brother\032MFC-6490CW. printer.tcp.local.) active for over two minutes. This places considerable burden on the network.
Sep 3 07:32:00 enterprise mDNSResponder[17]: Client application bug: DNSServiceResolve(Brother\032MFC-6490CW. printer.tcp.local.) active for over two minutes. This places considerable burden on the network.
Sep 3 07:37:21 enterprise mDNSResponder[17]: Client application bug: DNSServiceResolve(Brother\032MFC-6490CW. printer.tcp.local.) active for over two minutes. This places considerable burden on the network.
Sep 3 07:38:54 enterprise ntpd[44]: time reset +0.249989 s
Sep 3 07:42:31 enterprise mDNSResponder[17]: Client application bug: DNSServiceResolve(Brother\032MFC-6490CW. printer.tcp.local.) active for over two minutes. This places considerable burden on the network.

This is repeating OVER and OVER and OVER. I wanted to uninstall the printer - so I removed it from my printers list, and this error still continues. The software that came with the printer had a vise installer, but no uninstaller, and Brothers site doesn't have instructions for removing Brother Control Center. Any tips on how to get this issue to stop would be most appreciative.

Now, my other problem (which may or may not be related):

I don't see my network in shared places, nor can I see any systems on my network via shift cmdk. There are 3 other systems on my network that should show up - my wifes vista box, my droboshare and my HTPC. My wifes vista box shows all systems (including mine) so I know SAMBA is responding to requests of some sort. This is a workgroup environment, and I have confirmed that all systems are in the same workgroup (even if they weren't, you'd think I'd see multiple workgroups listed when I opened up Networks). I can connect to a share if I know the system ip and share name.

Any clues on these two issues would be most appreciated. I know 10.6 is so new, and I've not had any luck locating info on google regarding these problems...
