SCVMM 2008: Reports generated from OpsMgr 2007 SP1 in Japanese change back to English after a few days
You have an environment where SCVMM 2008 is installed with Operations Manager integration. When you run a report using the Japanese version of Operations Manager, the initial reports show up properly in Japanese. After about two days, when you go to run the report again, you will find the language is changed back to English.
This has confirmed to be a problem on the SC Operations Manager 2007 side. It has been a confirmed to be a bug in 2007 SP1.
There is no workaround although the issue has been fixed for System Center Operations Manager 2007 R2.
There will be no hotfix for SP1.
The best resolution is to upgrade the Operations Manager environment to 2007 R2.
