I have a small network with two computers (Windows XP), a Mac (OS X 10.6), a printer (Konica Minolta C250) and a server (Windows Server 2008 Standard SP2 x64).
Lately, after configuring a shared folder for scanning on the Mac, the Mac started to get really slow on startup, shutdown and sometimes in between too. In order for it to start/shutdown I had to take the network cable and plug it back in.
I ran Wireshark on the server to monitor the Mac requests and noticed a DNS request for the server's FQN by the Mac.
This was the output (IPv6 is deactivated in the Mac and in the Server):
"22857 1086.302117000 192.168.1.41 192.168.1.2 DNS 84 Standard query 0x3530 AAAA servidor.soengenho.local
22858 1086.302243000 192.168.1.2 192.168.1.41 DNS 131 Standard query response 0x3530"
The normal output to another computer is, for example (coming from a Windows XP machine):
"20138 948.242215000 192.168.1.40 192.168.1.2 DNS 84 Standard query 0xe413 A SERVIDOR.soengenho.local
20138 948.242215000 192.168.1.40 192.168.1.2 DNS 84 Standard query 0xe413 A SERVIDOR.soengenho.local"
If I do a nslookup, it answers correctly pointing at the server IP:
May this be the true problem causing the Mac startup/shutdown slowness? Or am I just wasting time with something unrelated?
