Hello,

I have this strange problem. In our company we use softphones from
Nortel.
There are some extra services installed on the PC's who use this
softphones:

QOS services from Nortel and the QoS packet scheduler from Microsoft.
Only
the people who have a softphone have a problem with double IP
addresses. The
computer who not using a softphone work well.....our server: NW6SP3
with
DHCP/DNS server ping enabled.
