I have been looking at problem of slow client login to a Win 2003 Domain.
I did a trace with Wireshark and identified two big waits.
No. Time Source Destination Protocol Info
2987 0.000067 192.168.0.103 192.168.0.250 TCP nim > netbios-ssn [ACK] Seq=182419 Ack=202615 Win=65135 Len=0
2988 19.827691 192.168.0.103 192.168.0.250 DNS Standard query SOA PC3.pctc.local
2996 43.571507 192.168.0.103 192.168.0.250 ICMP Echo (ping) request (id=0x0200, seq(be/le)=1536/6, ttl=32)
2997 0.000071 192.168.0.250 192.168.0.103 ICMP Echo (ping) reply (id=0x0200, seq(be/le)=1536/6, ttl=128)
Yes, over 1 minute wait on 2 packets!
192.168.0.103 is the client and 192.168.0.250 is the 2003 Server
The problem (delay) is repeatable, but not every time, so it appears to be something at the Server end.
Has anyone found this before?
Regards
Phil
