Hi!
I've made a Web Service using C# that is using impersonation.
The WS is working fine on WinXP and Win2003Server, but I'm having problem
getting it to work on Win2000.
The problem is that in order to use LogonUser on Win2000, you have to have
the SE_TCB_NAME privilege.
Therefore I'm using the SSPLogonUser
( http://support.microsoft.com/default...NoWebContent=1)
to authenticate the user.
This is working.
To be able to impersonate, I use the DuplicateToken API function.
This function takes a token as parameter, and I don't know how to obtain
that token.
When using the LogonUser function, you get a token in return, so on WinXP
and Win2003Server the problem doesn't arise.
I tried using WindowsIdentity .GetCurrent() after calling SSPLogonUser, but
it seems as if the token I'm getting is the wrong one.
Does anyone have an idea on how I can obtain this token?
Thanks in advance!
Regards,
Nils Magne Lunde 12  2664 
You should call QuerySecurityCo ntextToken to obtain a token from the
security package.
Note however that this token has no network credentials.

Ok, I see.
Is there an easy way for me to obtain the security context that is used as
input to this function, or do I have to make the SSPLogonUser return this
context?

When calling QuerySecurityCo ntextToken , you have to pass the adress of the
Server context handle (&asServer.hctx t), you could make this call before
returning from SSPLogonUser and return the access token obtained by calling
QuerySecurityCo ntextToken, or you could implement another function that
takes the context handle and returns the token? it's up to you ;-)

I got i to work on Win2000 Professional.
Now I only have to find a way to get it to work on Win2000 Server.
It seems as if the token is somewhat invalid, and I don't have access to
anything after impersonating using it.

What exactly do you mean with "I don't have access to anything"?
Note that the token obtained has not network credentials, so network
resources are not accessible when impersonating.

I mean that after impersonating with that token, I only have guest
privilegies on this computer.
On WinXP, 2003Server and 2000Pro I can impersonate any domain user, and
have access to the same resources as if I was loged in as this user. On
Win2000Server I only have guest privilegies no matter who I'm
impersonating.
The 2000Server I'm using is the pdc of our domain.
Could that be the reason?

I am a domain admin, so that shouldn't be a problem.
Could it be that impersonation using the techniques in SSPLogonUser is

news:op******** ******@news.mic rosoft.com... I mean that after impersonating with that token, I only have guest
privilegies on this computer.
On WinXP, 2003Server and 2000Pro I can impersonate any domain user,
and have access to the same resources as if I was loged in as this user.
On Win2000Server I only have guest privilegies no matter who I'm
impersonating.
The 2000Server I'm using is the pdc of our domain.
Could that be the reason?

Hi!
I've made a Web Service using C# that is using impersonation.
The WS is working fine on WinXP and Win2003Server, but I'm having problem
getting it to work on Win2000.
The problem is that in order to use LogonUser on Win2000, you have to have
the SE_TCB_NAME privilege.
Therefore I'm using the SSPLogonUser

Hi, all:
My asp.net application calles MS speech 5.1 and generate a wav file on

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
