Adding Active Directory Domains Stops K2 Services

Please confirm the version of K2 are you running? (I am assuming SP4 since you're running MOSS 2007).

 There is a hotfix for K2 SP4 to better handle more than 2 domains. Also, you may want to consider:

1. 
   
2. Reducing the refresh interval for ADCaching. Default is ot refresh every 10 minutes. This can easily overwhelm any machine for large volume/complex domain conditions if having to traverse/resolve the structure's memberships.
   
3. Reduce the number of domains and slowly add another one by one until the system experiences the symptoms again. This will assist in determining whether the specific domain condition is a factor (user/group volumes, deep nesting, domain/network latency to this domain, etc.) and/or a 'safe' threshold for the short term.

I would also highly recommend opening a support ticket if not already done.

Thanks for the response Dave. I don't know it the hotfix was applied. I will have to talk with our IT guys about that. We are using SP4 and I did change the ADCache a while back to 240 and then start adding domains. I get to the 4th domain and it stops. I will find out about the hotfix.

the SP4 hotfixes are accessible via a link on the Portal's "Downloads" > "Product downloads" > "K2.net 2003" page ("K2.net 2003 wih SP4" section has an obscure "(Click here for K2.net® 2003 with SP4 hotfixes)" option.

Look at Hotfix 3 (Multi-domain hotfix).

Does it happen when you add a SPECIFIC Domain as the 4th domain or with ANY domain as the 4th domain?
