This has to got to be so simple but I can't get it to work....
I am trying to update 2 fields per record based on the results of a query. I can run the query by itself and it returns the data but when i add the update piece it balks about a ")" issue. I can't seem to find out why or where to put the closing ")". What am I missing???

use netperfmon
UPDATE dbo.nodes
set totalports = c.totalports,
freeports=c.freeports
from (
SELECT c.totalports, c.freeports
FROM [MyServer]...[truecontrol.rn_device] as C
JOIN dbo.nodes as N
on N.caption = c.hostname)

this will work better:
use netperfmon
UPDATE n
  set totalports = c.totalports,
  freeports=c.freeports
from dbo.nodes n
join [MyServer]...[truecontrol.rn_device] as C
  on N.caption = c.hostname

c is not visible from outside of the brackets, and the update clause expects an alias of the derived table

try this

use netperfmon
UPDATE dbo.nodes
set totalports = tt.totalports,
freeports=tt.freeports
from (
SELECT c.totalports, c.freeports
FROM [MyServer]...[truecontrol.rn_device] as C
JOIN dbo.nodes as N
on N.caption = c.hostname) tt
