Troubleshooting and Limitations

Search for	Example	Results
A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`

Problem: Cannot Connect to Windows Vista/2008-R2 Machines with UAC Enabled

Reason: Starting from Windows Vista, Microsoft has changed the security mechanism by introducing the UAC (User Account Control) technology. This change causes problems with HPCmd connecting to remote Windows Vista/2008-R2 machines when using the local administrator account.

Solution: The following procedure enables HPCmd connection to remote Windows Vista/2008-R2 machines with UAC enabled.

Verify the HPCmd connection
1. Log on to the Probe machine.
2. Locate the HPCmd.bat file in hp\UCMDB\DataFlowProbe\tools directory.
3. Open cmd.com in the same directory.
4. At the command prompt, invoke following command:
  
  HPCmd.bat \\<problematic machine name or ip> /USER:<domain>\<username> /PWD:<password>
If the HPCmd connection is not successful, check accessibility to the shared folder, admin$.

Ensure that the Probe machine can access the shared folder, admin$, on the remote machine.
1. Log on to the Probe machine.
2. Select Start > Run, and enter \\<remote machine>\admin$ address.
3. If there is no access to admin$:
  - Log on to the remote machine.
  - Select Start > Run, and enter regedit.
  - Locate the following registry subkey:
  - Click Parameters.
  - If the AutoShareServer registry entry does not exist, in the Edit menu, select New > DWORD (32-bit) Value. Enter AutoShareServer, and click OK.
  - Select AutoShareServer. In the Edit menu, select Modify, and in the Value box, type 1.
  - Exit the Registry Editor, and restart the computer.
  - Select Start > Run, and enter net start srvnet.
4. When access to admin$ is successful, try to verify the HPCmd connection again as described in Verify the HPCmd connection.

If the verification still fails, connect to Windows Vista/2008-R2 machines with UAC enabled.

On Windows Vista/2008-R2 machines, local administrators do not have full privileges when connected remotely.

Use one of the following options to overcome this problem:

Connect using domain administrator credentials.
Enable local administrators to have full privileges by modifying the registry on remote machine as follows:

Key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Policies\system

Value

LocalAccountTokenFilterPolicy should be set to 1.

If this value is not available, create a new DWORD value and set it to 1.
