Powershell v2 remoting and delegation - powershell

I have installed Powershell V2 on 2 machines and run Enable-PsRemoting on both of them. Both machines are Win 2003 R2 and are joined to the same active directory domain and I can successfully run commands remotely. So PS remoting is working between the local server and remote server.
But when I try to access a share on a 3rd server (dir \someOtherServer\builds), which is also Win 2003 R2 and joined to the same active directory, I get the error:
Get-ChildItem : Cannot find path '\someOtherServer\builds' because it does not exist.
So what does it take to get this "hop" to work? Is it the delegation settings (in the active directory) to the remote machine? Are there any settings that can be done when creating a PSSession that will make the hop to work?

I addressed this issue for Workgroups in a blog post. I think the info should apply to domains but I haven't tested in a domain. Anyway, see if it helps. FYI, the solution involves Enable-WSManCredSSP and the Authentication parameter to Enter-PSSession.

It's can be many causes of that. If kerberos auth, check the time on all servers. It must be sync. It may be DNS resolution problem. Need more detailed problem description/
Sorry fo bad english :). If something wrong, please correct me :)

Remote Execution of "get-process" Fails, Couldn't Connect to Remote Machine

In my workplace, we administer hospital intensive care PCs (Windows 7 desktop clients) that are meant to be on and running a particular program in near-perpetuity. To that end we've developed a few powershell scripts that run every 5 minutes and alert us whenever the PCs drop off the network or the processes / programs we require crash.
Our program monitoring script relies on the powershell cmdlet "get-process" run remotely by an admin-credentialed account. The script works on all of our PCs except one and we haven't been able to determine what's causing the failure.
At its most basic, the command looks something like
get-process -computername [hostname]
When pointing toward our problem PC we get the error
Get-Process : Couldn't connect to remote machine
Our research indicates that this is likely caused by permissions, firewall, or remote registry service problems. We've triple-checked and on this PC and
the monitoring account has admin privileges, no firewall is active, and remote registry service is on and set to start automatically. The code works when run on the local machine but not when run remotely.
Similar powershell cmdlets run remotely, like "get-service", work with no issues. As noted above "get-process" runs successfully on our other PCs. Any insight into this strange issue would be appreciated.
One thing to note is that the Invoke-Command workaround that has been offered in answer to other, similar questions doesn't work on this PC or any of our others.
Have you tried validating the all RPC services are up?
1.Remote Procedure Call(RPC)
2.Remote Procecure Call(RPC) Locator
3.Remote Registry (You said it's up though)

Alfresco webdav credentials issue

We have deployed Alfresco community V5.0.d in my company.
I have to automatically mount alfresco server at startup thanks to Webdav protocol.
To do that, i’ve written a .bat file and put in on ours active directory servers :
net use w: /delete /yes
net use w: \IP:8080\alfresco\webdav\Sites\test\documentLibrary/persistent:yes
I have to specify that we have 2 AD servers (without the same structure) and ours workstation are under Windows 7.
The issue is that when we type ID/Password Alfresco in the credentials prompt at startup, it doesn’t work (but it works if I access to alfreso webdav thanks to internet navigator).
I’m trying to solve this issue.
Webclient service automatically starts. I have set the AuthForwardServerList key in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters on workstation :
IP:8080/share
IP:8080/alfresco
IP:8080
IP
It doesn't solve the problem.
Do you know how to fix this ? Can you give me some help ?
Thanks
I blogged the details after a sucessful mounting in windows 7 & windows 2008 R2 server.

I thing, your mouting details are incorrect.
Incorrect : \IP:8080\alfresco\webdav\
Correct : \\localhost#8080\alfresco\webdav\
Please use the "#" symbol in between the ipaddress and the port number.

Will a PowerShell script developed for a Windows 7 run on Win Server 2008 R2?

I have developed a large PowerShell script that has been refined on a Windows 7 64bit box and now I intend to run it on a Windows server 2008 r2. Assuming the PowerShell versions are the same, will there be any major issues with syntax in-between Win 7 and WS 2008 R2?
The script checks a lot of WMI and registry keys like GWmi Win32_NetworkLoginProfile and Get-Itemproperty -Path Registry::HKLM\Software\Microsoft\"Windows NT"\CurrentVersion\winlogon\
Most PowerShell information is driven towards managing servers so I assume I will be safe, but I want to see if you all can help me learn some lessons before I start banging my head against the wall.
Thanks
There are no syntax differences between PowerShell on Windows 7 and PowerShell on Windows Server 2008 R2. You may encounter differences in existing services, WMI classes, and registry keys, though.
First you should test it on a virtual machine to see if it works or not. Then try it on the physical machine. If it doesn't work, modify the code to the specific registry keys.
The short answer is yes. I run PSv4 on both my desktop and one of my servers running 08. Be sure to import the correct modules (if any) and allow for RPC in your firewall (And winrm) if applicable. One note- depending on what you run with the server, commands and functions are only as good as the version you run against (even when invoked). I ran into this problem as I scripted in v4 and environmentally my firm is almost all v2. Enabled -verbose error output and test in virtual machines or a loner laptop. (This is what I did). Good luck!

PowerShell v2 Server 2003 - Cannot Find Path - Path definitely exists

Usually I can find an answer to PowerShell questions by researching forums and adapting. However, after searching high and low, I cannot find an answer.
I am logged in as a domain administrator working on two enterprise servers in a test domain. $Server2003 is Windows 2003 server running PS v2. $Server2008 is Windows 2008 R2.
Problem: When I am working from $Server2003 I cannot use any commands to access or verify information on $Server2008. This error happens regardless of who the administrator is.
I have used PowerShell fairly extensively in our environments and haven't run into this error before. The error is not present when running commands from $Server2008 on $Server2003. In addition the error is not present when running commands from a production domain. I can also ping the 2003 or 2008 server regardless of which machine I am logged in as.
Examples:
From $Server2008: ping $Server2003 - returns pings
From $Server2003: ping $Server2008 - returns pings
From $Server2003: test-path \\$Server2008\D$\ - Get-ChildItem : Cannot find path '\\$Server2008\D$\' because it does not exist
From $Server2008: test-path \\$Server2003\D$\ - True
The commands I want to run are a lot more complex than test-path; however, if I cannot get the simple command to work I doubt I'll have much luck with a complex one.
The two servers have the same domain, are in the same forest, and have the same domain controllers.
Any ideas where to start?
EDIT: Wanted to add that I have tried using test path from Server2003 to a different 2008 server located in our dev environment (same domain) and it runs the test-path and commands successfully.
can you access the 2008 server remotely by other means? Like the Services MMC? Also, what if you create a share on 2008 rather than rely on the admin share?
The cannot find path error means that it doesn't exist or you don't have permissions. Does it work from a dos prompt?
UPDATE
I just noticed that you used single quotes, the variable will not expand. Enclose it in double wotes and try again

PowerShell Remoting to many servers across domains

I am DBA. I am trying to write bunch of scripts that I could execute from one central server. Ideal would be to send all the scripts from central server to say 50+ servers across multiple win domains (for databases management purposes).
The problem I am running into is - security. Seems like PowerShell Remoting is the way to go. But when I send a script to another server, I get 'not digitally signed' error.
I could 'self sign'. But that cert if only trusted on local machine. So that option is out.
Maybe Certificate Authority is a way to go. Or adding trusted hosts. I just have no clue on this one, so if you know any blog posts or how to do this - it would be big help.
Well, it's a security risk, but there's always the possibility of setting the execution policy to RemoteSigned, keeping a local repository on each server and calling those as needed via PS-Remoting. I don't like that idea one bit though.
If you are doing remote execution, you will need to sign your scripts. A detailed step by step can be found here. It even covers deploying the cert via GPO so that it's domain trusted.
I would use PowerShell remoting. This would allow you to run it as remote commands instead of remote scripts. If you catch the bottom of this SimpleTalk article, after "Persistent Sessions". It shows the option of executing a set of commands against each server instead of the script. This should prevent having to deal with the remote signed issue and provide a little more control.
The only thing to deal with on remote sessions is your credentials. I have not tried this on multiple domains but a few stand-alone servers.
