Are you doing OK now? Did you file an SCC Bugzilla on this? If so what is the bug number?
There is essentially no difference between 126.96.36.199 and 188.8.131.52. The only difference is a fix to the sccProductiontest program, which external users hardly ever use. Don't use 184.108.40.206 or 220.127.116.11 because they are unstable.
If your problem still persists and you have a bug number, we can continue the discussion on Bugzilla.
