Hello-
I have an interesting issue regarding increasing ping times either by
dns name or by ip. When pinging the Exchange server or otherwise over
a site to site vpn (dsl)... The ping times initially are 120ms then
increase by approx 100ms easch ping afterward until I stop the Ping -t.
Usually at 1000 ms.
Any one have a theory? The tracert is fine: 120ms to the destination.


I am asking b/c all of a sudden at this remote site Exchange is moving
very sluggishly (outlook rather). IT Receives okay, but sending is a
nightmare. I am thinking DNS issues and duplicate ip issues, b/c
internet access out of the remote site (non vpn) is fine, Mapped drives
are fine.

Back to the question.. Any theories other than mine out there or
agreements? Can't test til Monday.

Thanks!

Couple of things. If you can ping by IP and by DNS and it shows the
same symptom, you can pretty much rule out name resolution issues. I'm
thinking someone is artificially rate limiting your ICMPs. Perhaps you
are using tracert from the router or a Unix box? It uses udp so it may
not be affected like ICMP pings.
