Question 4: No Memory or Uptime Showing

Again, I have 7 windows servers being monitored.

On one of them, it shows OK for Memory and Uptime, but, for memory it shows:

Memory usage: total:0.00 Mb - used: 0.00 Mb (nan%) - free: 0.00 Mb (nan%)

and for uptime:

System Uptime - 0 day(s) 0 hour(s) 0 minute(s)

but they are both green, all the other services on the machine report correctly, any ideas?
