Microsoft has recently launched a new space at Microsoft Technet Forums for Operations Manager 2007 R2. You will find it here. The old NNTP based news group will be closed down. See you at Technet Forums!
Operations Manager forums provides you an opportunity to join a community of Operations Manager customers, product team, MVPs and experts, where you can share knowledge, get questions answered and learn from others. Start by posting Operations Manager related questions in the forum corresponding to your topic of interest and leverage the knowledge available in your new forum community.
