Question: PSTools I downloaded and installed in C: \ PSTools. Then I did the following:

1 - I opened the Command Prompt

2 - C: \ PSTools> I did this: C: \ PSTools> `psexec`

3 - Then I did: C: \ PSTools> `psexec \ \ IP-u user calc`

But it returns this message:

Can you help me??
Thanks,

Answer: 
1.exzip the pstools anywhere， such as d:\pstools\

2.use cdm , and switch to d:\pstools

3.type 

```
 psexec -u Administrator -p password \\192.168.1.111 netstat -na 

```

to test it!

it will show the message of 192.168.1.111. 

if show error message: 

Error initializing crypto: object is already exist.

then you must：

2-1.use cmd with Administartor's Power.

or

2-2.use cmd , and tyep "run as ..." to pop out a administrator cmd, and use it.
First try pinging the machine so you know you have access over the net.  

Then try turning the fire wall off.  

If this works you know you have a valid path between the machines. Then you have to figure out how to run it with the fire wall still on.
