# Works when we only specify a destination directory
Copy-Item -Path testfile.txt -Destination C:\ -ToSession $session

# Doesn't work when we specify a filename
Copy-Item -Path testfile.txt -Destination C:\testfile.txt -ToSession $session

# Even if it's different from the original filename
Copy-Item -Path testfile.txt -Destination C:\testfile2.txt -ToSession $session

# Here is the output I get for the first failed command

WMF 5.0 lets you create DSC Resources using Powershell Classes like so:

[DscResource()]
class My_DSC_Resource
{
...
}

But right now it will only look in the .psm1 file. If you try to dot source a class based DSC resource into the .psm1 file then Get-DSCResource can't find it and it can't be used in DSC configurations.

We have many DSC resources combined into a single module, and our .psm1 file is getting difficult to manage. If two people are working on different resources they are likely to have a git merge conflict.

We would prefer to have the resources defined in separate files and then dot source them into the .psm1 file, similar to how other modules are designed.

Install-PackageProvider cannot retrieve the list of available providers if the machine doesn't have direct access to the internet.

How to reproduce:
1. Setup a network completely separate from the internet.
2. Setup an HTTP-proxy in that network as following:
2.1. The machine with HTTP-proxy has 2 network interfaces: 1 connected to a LAN and another one - to the internet.
2.2. Configure the proxy in a way to require authentication, not allowing anonymous connections. Configure Kerberos authentication.
2.3. Allow access to the internet via the proxy for AD user accounts only, not for the computer ones.
3. Publish the proxy with WPAD.
4. Use Group Policy to configure Internet Explorer throughout the network to use WPAD as a source of proxy settings.
5. Try access the internet (http://example.com) via Internet Explorer - everything works fine.
6. Launch PowerShell console as an administrator, using AD account allowed to access internet via the proxy.
7. Try to download NuGet provider using Install-PackageProvider cmdlet - you receive an error shown above.

If a Node is configured using a RegistrationKey so that ConfigurationNames can be used, then the CertificateID attribute is ignored under the ConfigurationRepositoryWeb block, and instead a self-signed certificate is generated called "DSC-OaaS".

This certificate is used for both client authentication to the pull server as well as encrypting configuration Mofs at rest on the server host.

The problem is two fold:

1. Becuase the CertificateID gets ignored when using CONfigurationNames, admins cannot control the key length or encryption of the files.

2. The certificate generated is a SHA-1 1024bit length. This is completely unacceptable as 1024 went out of use years ago, and SHA-1 is getting retired this year as an encryption standard.

Please allow administrators to select the certificate for use and NOT force a weak self-signed certificate.

In WMF 5.0 (tested on Win7 w/ KB3134760 and Win10 10240), the presence of certain Import-Module statements in a module in $env:PSModulePath will cause Get-Module -List to throw. In particular, if a module attempts to import another module with a path relative to $PSScriptRoot, it seems to break things. We do this type of thing within psm1s in cases where a manifest cannot express the behavior we need. Here's a repro:

## On Win7, using the re-released WMF 5.0 (KB3134760):

PS C:\> gwmi win32_operatingsystem | fl caption, version

## Say I have a directory of modules added to an otherwise stock %PSModulePath%, in this case C:\local\dummy:

PS C:\> $env:PSModulePath
C:\Users\whitema\Documents\WindowsPowerShell\Modules;C:\Program Files\WindowsPowerShell\Modules;C:\Windows\system32\WindowsPowerShell\v1.0\Modules;C:\local\dummy

## In that directory, I have two very simple modules with one function each, foo and bar. foo imports bar using $PSScriptRoot

PS C:\> ls -rec C:\local\dummy

Directory: C:\local\dummy

Mode LastWriteTime Length Name
---- ------------- ------ ----

PS C:\> cat C:\local\dummy\foo\foo.psm1
Import-Module (Join-Path $PSScriptRoot '..\bar')
function Get-Foo {'foo'; Get-Bar}
PS C:\> cat C:\local\dummy\bar\bar.psm1
function Get-Bar {'bar'}

## Now, get rid of any existing CommandAnalysis cache and make sure I'm in a fresh shell, otherwise this many not be reproducible, then run Get-Module -ListAvailable. This works without specifying the module name too, it's only shown here to limit the output. DO NOT PRESS TAB WHILE DOING THIS, it may cause a command analysis cache file to be created and break the repro.

PS C:\> get-module -list foo
get-module : The specified module '(Join-Path $PSScriptRoot '..\bar')' was not found. Update the Name parameter to
point to a valid path, and then try again.

## While attempting to debug this, I also noticed some strange behavior - in the debug shell $PSScriptRoot appears to be an empty string, but it seems to work in spite of that. I've also seen a scenario where the variable object from get-variable showed the expected path, but just using $PSScriptRoot evaluated to an empty string. I can't seem to repro that behavior reliably though. This does not cause any problem beyond confusion, but I'm mentioning it because perhaps it's related?

Apparently Sysprep on Windows Server 2012 doesn't know what "sysprepOrder" is.

Workaround: Delete the added stanzas, then sysprep runs to completion without errors.

So, it seems as though in WMF 5.0 there is a regression in functionality. In WMF 4.0, you could set up a DSCFileDownloadManager and Credential to have a Target Node contact a Pull Server SMB Share and download new mof files and resources. Everything worked perfectly including Certificate based encryption of the credentials. However, in WMF 5, it seems as though the LCM of the Target Node attempts to contact the SMB Share Anonymously, even in credentials are provided. Now, in a Non domain joined environment, you can just provide EVERYONE full control and then change Local Security Policy such that Anonymous=Everyone (even though this is a massive security risk in an enterprise environment). However, even worse, in a Domain Joined environment, there is no workaround. As the LCM cannot contact the LCM anonymously anymore (at least with no settings I saw), it instead attempts to contact the SMB share as the Computer Account, which of course will fail. This also makes it untenable to provide EVERYONE access because they will still get denied. I haven't found a workaround to get SMB Share working at all in a domain joined environment. Obviously, all of this worked in 4.0 including Certificate encryption with DSCFileDownloadManager. With 8.1 and beyond now offering SMB Encryption as well, the DSCFileDownloadManager is still a viable enterprise solution, and thus a potentially major issue.

If there are any workaround in the mean time, I'd love to hear them. Also, if I have misunderstood/misimplemented the issue, I'd love to hear that too. I did a wireshark capture of the traffic and it appears pretty cut and dry.

Thanks

Problem Description:
It would be great if PS ISE had a "Save All" files feature to save all open, unsaved files. This is considered standard functionality in most IDEs these days, and it is typically bound to the keyboard shortcut Ctrl+Shift+S. Basically the same functionality as Ctrl+S, just iterate over all open, unsaved tabs and do the same.

Expected Results:
Hit Ctrl+Shift+S and all open, unsaved files are saved, prompting you for a path to save a file to if necessary.

Problem Description:
The Find-module command needs some further improvements to allow there to be better discoverability of functions and Modules including the ability to search for functions using Wildcards and also to get back results based on the functions Synopsis, Description, Function Name, Notes & Examples

An example of a better formatted Find-Module command could be

Find-Module -Command '*SharePoint*' and this should return all modules that contain functions that relate to SharePoint

If implemented to Search all the above mentioned areas then this will really drive the adoption of the Gallery and will enable the community to ensure that the best modules are created and can be shared/extended/improved to mitigate poor practises going forward.

This will also need to be implemented for the DSCResource parameter as well.
