Hi Ron,
I think it basically means your code is wrong.
I don't use C++ for this type of thing, so can't help much, but I note you are using RPC_C_IMP_LEVEL_IMPERSONATE, but you say you are passing credentials? That's probably not correct.

Hi,
Yes, WbemTest successfully connects with the same credentials I use in the code which won't work for queries (but will connect successfully).
Any ideas?

I have my own c++ code to connect to WMI servers and run queries. It works
locally perfectly however when I use the same code for this remote server
with the user id + password, it connects successfully, but executing queries
gives me the good old "access denied":
Connected to ROOT\CIMV2 WMI namespace <- connection works nicely.
Query for operating system name failed. Error code = 0x80070005 <- query
fails! same query works fine using WMI explorer.
My question i guess is whether I'm doing something wrong with the
CoSetProxyBlanket. My implementation is:
hres = CoSetProxyBlanket(
pSvc, // Indicates the proxy to set
RPC_C_AUTHN_WINNT, // RPC_C_AUTHN_xxx
RPC_C_AUTHZ_NONE, // RPC_C_AUTHZ_xxx
NULL, // Server principal name
RPC_C_AUTHN_LEVEL_CALL, // RPC_C_AUTHN_LEVEL_xxx
RPC_C_IMP_LEVEL_IMPERSONATE, // RPC_C_IMP_LEVEL_xxx
NULL, // client identity
EOAC_NONE // proxy capabilities
);
any help would be appreciated.
Ron
