I have been using ipscan.exe for years. It's a great little tool that will list everything on a network, including switches, hubs, printers, workstations, etc. Recently I have been unable to access the program. I get the message Access to the specified path or file is denied. The banner at the top of the window that pops up giving the message lists the path of the file, for example c:\windows\system32\ipscan.exe. I normally run this from a Windows 2000 workstation, but I am getting this message from all the workstations (Windows XP Pro) and servers (Windows 2000 and 2003 server). Is there any way of telling when access is deined, why access is denied? That would be a big help?
