I've an ADSL connection and am using a D-LINK DSL-502T router provided by my ISP. I'm also using p2p apps. such as eDonkey and eMule. By default, the ports that these apps. use are not open in the router. I manually opened these ports in my router, but these apps. still show that they're unable to connect and the mentioned ports are still not open. I've also checked in the router control panel that the router's firewall is inactive. I'm using WinXP Pro (without SP1 or SP2), but I've not enabled the Internet Connection Firewall either. A quick check over at http://www.grc.com tells me that the ports I've opened are "Stealth". I don't use any software firewall either, because my ISP informed me that the router itself would be enough. Also, to achieve maximum out of my PC & WinXP, I've disabled some of the services that are by default "On" in a default WinXP environment. The services I've running are: COM+ Event System, Computer Browser, Cryptographic Services, DHCP & DNS Client, Event Log, Network Connections, Plug and Play, RPC, SAM, Server, System Events Notification, Terminal Services, Windows Audio, WMI and Workstation. Do you think my problem exists because I've disabled some of the Windows default services? Any suggestions? Thanks.
