I guess it depends on how long ago your support department was testing on it. The windows version is very stable and used by many of our customers that have windows servers rather than linux. No major complaints that we've heard from them.
Thanks for the information. Since a long time I was looking for someones genuine review on Enkompass, and as of now I have got it from you; so now I am going to shake our guys belly; hope this time they can understand me I will try to include Enkompass in our Windows hosting plans soon...Thanks again...
