Dear Friends..

today i got a mail from my client that they getting loads of SPAMs .. thought lets check TMG .. but there is no configuration in nay of my TMG servers.. when i see my TMg console .. first it is not opening up.. and if it is .. then its not showing any configuration... guys this is very critical and urgent ... please help

UPDATE : .. :(

i got 2 TMG servers and that was configured with another TMG store server for the configuration ... which was a virtual server.. now by mistake we deleted that HDD for the store server... so both the TMG are without config server now .. is there any thing which can be done .. i have my production clients on this .. please help ...
