Dear All, Hi How are you all.. having a great time !! ?? but I am not. I am having some serious issue with a workgroup network trial with my 2 PCs at home, in which both of them are having Windows XP – SP2. SCENARIO: I have networked using INTEL 100/Pro S PCI network card with RJ 45 CAT 5E media connected to BAYSTACK 420 24 port SWITCH and then internet ADSL router – SPEEDTOUCH is also connected to this switch. PCs are both assembled ones, with original INTEL 800Mhz FSB Motherboards with Original Boxed INTEL P4-E processors @ 3.0 Ghz (1MB Cache) IP ADDRESSes: ADSL router (in-built DHCP server enabled, Range=10.0.0.1 – 254 / ff.ff.ff.0) 10.0.0.138/ff.ff.ff.0 Baystack switch = 10.0.0.5 / ff.ff.ff.0 PC no.1 = 10.0.0.10 / ff.ff.ff.0 PC no.2 = 10.0.0.11 / ff.ff.ff.0 PROBLEM: I am able to PING / TELNET the ADSL router and Baystack switch successfully no issues. But I am not able to PING / TELNET to my two PCs. Also these two PCs I am failing to configure in a small WORKGROUP to share some resources. As per my friend’s advice, I have tried disabling the FIREWALL of SP2 and also the FIREWALL of TREND MICRO Internet Security Suite with Antivirus. Still I am not able to PING or configure a WORKGROUP. I have tried the Small Office / Home networking wizard. Still nothing works. So anyone faced similar problems and had a way out of it? Please do help me too. I am totally confused and believe me, feeling very bad because its just such a small interconnectivity and I am facing a tug of war in this. Thanks in advance , please do help. HAVE A NICE DAY !!! CHEERS !!
