Hi,
i see that issue is more likely with the SBS server , and i would recommend you to post your query under appropriate sbs group . If SBS group feels the issue is not with them , we are more happy to assist you further.
Regarding the Windows Small Business Server issue, please post to the Windows Small Business Server discussion group. The support professionals there are better equipped to assist you.
For your convenience, I’ve included the link of Windows Small Business Server discussion group:
