You don't tell what exactly is going wrong there but I have some suggestions anyway:
Here you compare two constant strings, it will never be
true
:
if ("cmb.Name" == "cmbServer1")
Probably you meant to do this:
if (cmb.Name == "cmbServer1")
I would advise against hard-coded references to a Form from another Form. It will be no issue in a very small project but if you add more Forms to your project or stick to that "strategy" when doing bigger projects, it will eventually result in a maintenance nightmare. There was recently a new article on this topic published here, take a look:
