[LDM #RAN-400269]: intermittent ldmadmin check error



David,

It's likely that one or more of the time servers the "ldmadmin check" command 
is using is incorrect. The servers are set in the registry parameter 
"/check-time/ntpdate/servers". You should have some good time servers at GSFC. 
Try using them instead.

Alternatively, you can disable time-checking by setting the registry parameter 
"/check-time/enabled" to 0. I don't recommend this, however.
