Hi, Got fujitsu-siemens laptop with Windows vista. network schema is following juniper SSG20 (does wifi) <-> HP switch (plain conf) <-> SBS2011 (does dhcpd) When laptop has Vista it is comletley blocked from network, does even get IP address. In all other networks it works, just not in this patricular one. When installed Windows 7 everything works fine. Couple months ago I remember testing with scenarios 1) dhcp server on juniper 2) dhcp server on linux server in same 192.168.1.0 network but this had no positive effect. In short has anyone experienced something similar? Any solutions , ideas ? Thanks.
