XP SP2 Firewall

[Guest]

Hi All

I have a windows service installed on Machine having XP2 Service pack 2 OS

I am using this call in Run() Method
hr = CoInitializeSecurity(NULL, -1, NULL, NULL,
RPC_C_AUTHN_LEVEL_NONE, RPC_C_IMP_LEVEL_IMPERSONATE, NULL,
EOAC_NONE, NULL)
If i access this service from other computer it gives access denied error

If i disable Firewall security from Control Panel->Windows Firewall,and in Dcomcnfg add ANONYMOUS user and give it full access
access denied problem goes

Why do i want to add ANONYMOUS in Dcomconfg even i disable Firewall security?

if i dont want to do all above settings but still my service should be accessed from other computer ,what should i do,is there any way for this?

Any help is appreciated

Thank
Tushar Mahajan

Firewalls are firewalls.
If something should go through it needs to have
a setting made in firewall to allow this.

Relative to your CoInitializeSecurity call, you need
to stop using NULL and providing real security defs.
Nulling out security is why we have such problems
on the network !! And you are right, there is no good
reason whatsoever to allow Anonymous any DCom
privileges, in fact, that aren't even any bad reasons.
