When opening a case with support one of the key bits of data that will help with a speedy resolution is, besides the error description, is patch output from each client involved.
this data can be gathered by running omnicheck -patches from the Cell Manager and also using the variable to query all clients involved in the issue by running with the host variable
ex;
omnicheck -patches -host HostName
omnicheck can also be used to get version information as well as SSP patch information
ex
omnicheck -version | -help
omnicheck -dns [-host HostName | -full] [-verbose]
omnicheck -patches -host HostName
omnicheck -ssphf -host HostName
