PRB: Adding a Cluster Member May Delete Existing IP Addresses on the Target Server
This article was previously published under Q287672
In Application Center 2000, when you use the Add Cluster Member Wizard or the
CLUSTER command line tool to add a new server to an existing cluster that is using network load balancing (NLB), the existing IP addresses on the target server may be replaced by the specified dedicated IP address (DIP) and/or the current cluster's IP address configuration.
This behavior is by design. Servers in an Application Center 2000 cluster that is using NLB must have identical IP address settings (other than dedicated IP addresses) on the load-balancing network adapter to ensure proper operation of NLB.
Steps to Reproduce Behavior
The following sample command line will effectively replace all IP addresses bound to the NLB-enabled adapter on the target computer with the specified dedicated IP address (DIP) and the current cluster's IP address configuration.
AC CLUSTER /Y /ADD /CONTROLLER:Server01 /MEMBER:Server02
/USER:Domain\Username /PASSWORD:***** /DEDICATEDIP:192.168.0.2
/DEDICATEDIPSUBNETMASK:255.255.255.0 /LBNIC:0 /MANAGEMENTNIC:1
APPLIES TO
- Microsoft Application Center 2000 Standard Edition
Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
