I am working in a large corporate environment where I have to support around 2500 PCs in different sites. I had lots of XP SP1 pcs and there was a urgent need to install SP2 in all of them. What I had was I installed GFI security scanner in my PC and scanned all the Pcs and pushed SP2 remotely. Every thing went perfect and around 100 Pcs were successfully patched with latest SP. I am using a remote connectivity software called Dameware which is using port 6129 by default. As soon as I patched the latest SP in those PCs I am unable to connect them remotely. I am also unable to get them through remote desktop conection.
Now is there any way that I can either switch off the firewall or get the port 6129 opened in all the pcs without the internevtion of system administrator. I am a local admin of all the pcs in my office.
