cameron,

В логах пусто, (в данный момент).

Единственное, в событиях имеется ошибка:

ISA Server detected a network adapter connected to multiple networks: Address 192.168.50.230 belongs to network 'Internal' and address 192.168.7.80 belongs to network 'External'. Verify that all the IP addresses on the network adapter are in the same network, or change the IP addresses on the network adapter. Дополнительные сведения можно найти в центре справки и поддержки, в "http://go.microsoft.com/fwlink/events.asp".

Description: ISA Server detected routes through the network adapter LAN that do not correlate with the network to which this network adapter belongs. When networks are configured correctly, the IP address ranges included in each array-level network must include all IP addresses that are routable through its network adapters according to their routing tables. Otherwise valid packets may be dropped as spoofed. The following ranges are included in the network's IP address ranges but are not routable through any of the network's adapters: 192.168.7.0-192.168.7.255;. Note that this event may be generated once after you add a route, create a remote site network, or configure Network Load Balancing and may be safely ignored if it does not re-occur. The routing table for the network adapter WAN includes IP address ranges that are not defined in the array-level network External, to which it is bound. As a result, packets arriving at this network adapter from the IP address ranges listed below or sent to these IP address ranges via this network adapter will be dropped as spoofed. To resolve this issue, add the missing IP address ranges to the array network. The following IP address ranges will be dropped as spoofed: Internal:192.168.7.0-192.168.7.255;

А у серверов из подсети 192.168.7.* обязательно должен стоять ISA сервер в качестве шлюза?
