Admin shares not accessible after SP3 upgrade!

[Innocent Devil]

I recently upgraded one of the SP2 running PC to SP3 in the Domain

But nw the admin shares are not accessible via

\\<comp-name>\C$

I tried from XP SP2 systems running within the subnet and W2k3 Ent Server also.

but the share can be mounted on remote computer using

net use * \\<comp-name>\c$ /user:<comp-name>\administrator * /persistent:no
