I am getting so frustrated by trying to use my MacMini as a server to my kids' laptops running Windows (XP, Vista, and 7). I have been surfing for weeks now trying everything I can find and I keep having troubles. I don't know if the troubles I am have are all linked or several problems, so I bullet out the problems: Mac not keeping IP address I tried to assign from my router (Netgear) using the mac address to identify my Mac. The Mac will end up with different IP addresses, but rarely the assigned one. I have tried to setup a domain name on the Mac, but it isn't always recognized on the PC's. Many times I have to use the IP address but, as described in the first bullet, this is a moving target! Epson printer being found shared from my Mac but not being able to print to it. Nothing prints or shows up on the printer monitor. Trying to map a network drive on the Mac from a PC by using the username and password set up on the Mac. Since I want to be able to keep security and not share the entire harddisk, I am trying to attach the remote PCs using the Mac username and password. The PC just doesn't recognize it. I have set the Workgroup to be the same on all PC's and the Mac. I have turned on Windows sharing (SMB) for both Printer and File. I have set a dynamic Global Host name (which is set the same as the WINS NetBios name). I have set my Netgear router to assign an IP address to a particular mac address (which happens to be the same as my network controller in my MacMini since I am hardwired to my router). I am using a MacMini with Snow Leopard Max OS X 10.6.2 (not the server version - is this my problem?). I hope someone can help me! I have been a PC guru for 20 years. This is my first taste of Mac now that I am sick and tired of Microsoft and Windows! So far, I love how fast the Mac is, but I am not impressed with the networking! Yet! Thank you.
