I am running SW2007 on my laptop which I also use as my desktop at the office. When I am logged on the the computer with administrator rights, I have no problems. However, when I am at the office and I log into the company domain, SW will not allow me to save .slddrw files to .dwg. I can save as .pdf to a network drive , but not .dwg. I get "unsupported operation" message. My network login has administrator rights on the computer.
