Unable to connect to MKS: Virtual machine config file does not exist

Guys,

Need a little help I'm running the following

vCenter Server 4.0.0 (build 208111)

ESX Server 4.0.0 (build 208167)

I have a VM running WIndows 2000 Advanced and when I try and open the console I get a black screen and the followin error messsage

" Unable to connect to MKS: Virtual machine config file does not exist".

I've browsed the datastore and all the VM files appear to be in place, I was thinking of deletin the VM from the inventory and re-adding the vmdk file, would this be a good idea?

Thanks.
