• Windows 7 mapped drive kicking off OS X users

  - by Collin White

  I've mapped a network drive on my Windows 7 PC at my office. The windows machine has a few TB of storage that is being accessed by my development team (all running mac os 10.7). The share seems to work fine for a little while but will timeout and kick the mac users off and sometimes disallows a connection on the next attempt. Restarting the windows machine fixes the problem. I've tried this tutorial as well as setting the maximum session length in the Local Security Policy section to 99999 (I discovered 0 did not mean unlimited, only a 'reasonable ammount of time') anyway, the setting is now for ~208 days which is sufficient (see attached). I'm having trouble debugging this in general so if anyone has some pointers I'm all ears. This is a intermittent issue which in my opinion are the hardest kinds to debug. If anyone knows of how I might monitor connections from the PC that would also be pretty cool. Previously the files were hosted on a mac mini and everything was working just fine (the mini just didn't have the ability for the storage capacity we needed) so I believe it is some windows setting that is kicking users off. Anyway, thanks for reading.

• Controller Error: Do I need to worry?

  - by Kryten

  I have a HP Pavillion dv5224ea Laptop with Windows 7 on it. Recently I discovered a Error in Event Viewer: The driver detected a controller error on \Device\Ide\IdePort1.

Event Viewer is recording A LOT of these errors (sometimes 13, one after the other!). Do I need to worry? What does this error mean? What device could "\Device\Ide\IdePort1" be? What is a ATAPI Error? Do I need to re-install Windows? I generally find the occurs when I try to backup my machine (using Windows Backup) or when using a program that uses Volume Shadow Copy. I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

• New tomcat install on OSX choking on startup.

  - by baudot

  I've completed a fresh install of Tomcat6 on an OS X box that didn't have it before. It's behaved a bit strangely in other ways, but the current hang-up is that it won't start at all. In response to running startup.sh, the catalina.out log collects this error: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/catalina/startup/Bootstrap Caused by: java.lang.ClassNotFoundException: org.apache.catalina.startup.Bootstrap at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Other bits of strangeness noticed with this installation: the .sh scripts in the bin directory had no execute permission, and had to be manually chmodded. The log folder wasn't created, causing an earlier script crash. After I manually created the log folder, the startup script made it to this new error before failing. Running other scripts in the bin folder generates similar error messages involving NoClassDefFoundError. Bootstrap.java is indeed in the right place, though Bootstrap.class isn't in the same folder. For that matter, if any of the myriad class files for tomcat should have already been generated from their .java files, I haven't seen it.

• Samba between Ubuntu server 10.10 and Windows Vista, Windows 7

  - by chepukha

  I have a linux box running Linux server ubuntu 10.10. I have installed Samba on this linux box and want to share files with my laptops which run Windows Vista home and Windows 7 home. I have been struggling with the setup for almost a month but couldn't get it right. If I try to access share folder from Windows Vista, I get message "Windows cannot access \\server_ip_address". Error code: 0x80070035. The network path was not found. If I access from Windows 7, then after entering password to login I can see the list of share folders on Linux box. But if I click on a share folder, I get the same error message as above. Tail /var/log/samba/log.windows7-pc I got the following message: [2011/03/16 00:17:41.427238, 0] smbd/service.c:988(make_connection_snum) canonicalize_connect_path failed for service sharemedia, path /root/sharemedia Here is my setting in smb.conf [global] share modes = yes netbios name = Samba workgroup = WORKGROUP wins support = yes encrypt passwords = true [sharemedia] comment = Tesing sharing using Samba path=/root/sharemedia/ public = yes valid users = samba_usr_name ; make sure all files are sensible permissions create mask = 0660 force create mask = 0660 directory mask = 2770 force directory mask = 2770 directory security mask = 0000 ; Normal share parameters read only = no browseable = yes writable = yes guest ok = no

• Why does redis report limit of 1024 files even after update to limits.conf?

  - by esilver

  I see this error at the top of my redis.log file: Current maximum open files is 1024. maxclients has been reduced to 4064 to compensate for low ulimit. I have followed these steps to the letter (and rebooted): Moreover, I see this when I run ulimit: ubuntu@ip-XX-XXX-XXX-XXX:~$ ulimit -n 65535 Is this error specious? If not, what other steps do I need to perform? I am running redis 2.8.13 (tip of the tree) on Ubuntu LTS 14.04.1 (again, tip of the tree). Here is the user info: ubuntu@ip-XX-XXX-XXX-XXX:~$ ps aux | grep redis root 1027 0.0 0.0 66328 2112 ? Ss 20:30 0:00 sudo -u ubuntu /usr/local/bin/redis-server /etc/redis/redis.conf ubuntu 1107 19.2 48.8 7629152 7531552 ? Sl 20:30 2:21 /usr/local/bin/redis-server *:6379 The server is therefore running as ubuntu. Here are my limits.conf file without comments: ubuntu@ip-XX-XXX-XXX-XXX:~$ cat /etc/security/limits.conf | sed '/^#/d;/^$/d' ubuntu soft nofile 65535 ubuntu hard nofile 65535 root soft nofile 65535 root hard nofile 65535 And here is the output of sysctl fs.file-max: ubuntu@ip-XX-XXX-XXX-XXX:~$ sysctl -a| grep fs.file-max sysctl: permission denied on key 'fs.protected_hardlinks' sysctl: permission denied on key 'fs.protected_symlinks' fs.file-max = 1528687 sysctl: permission denied on key 'kernel.cad_pid' sysctl: permission denied on key 'kernel.usermodehelper.bset' sysctl: permission denied on key 'kernel.usermodehelper.inheritable' sysctl: permission denied on key 'net.ipv4.tcp_fastopen_key' as sudo ubuntu@ip-10-102-154-226:~$ sudo sysctl -a| grep fs.file-max fs.file-max = 1528687 Also, I see this error at the top of the redis.log file, not sure if it's related. It makes sense that the ubuntu user isn't allowed to change max open files, but given the high ulimits I have tried to set he shouldn't need to: [1050] 23 Aug 21:00:43.572 # You requested maxclients of 10000 requiring at least 10032 max file descriptors. [1050] 23 Aug 21:00:43.572 # Redis can't set maximum open files to 10032 because of OS error: Operation not permitted.

• Server 2008R2 in Extra Small Windows Azure Instance?

  - by Shawn Eary

  Windows Azure hosting for an Extra Small (XS) Windows VM seems to come out to be about $10 a month right now. I think this XS instance gives you the equivalent of a 1 GHZ CPU with 768MB of RAM. I think the minimum requirements for Server 2008 is 1GHZ CPU with 512MB of RAM. Also, I think the minimum requirements for SQL Server Express is 1GHZ CPU with 256 MB of RAM and that the minimum requirements for Team Foundation Server Express 11 Beta is 2.2 GHZ CPU with 1 Gig of RAM (this 2.2 GHZ part could be a problem for my 1 GHZ XS VM...). Given the performance of the XS Azure instance, would I be able to install: a very basic MVC web site; a free instance of SQL Server Express; a free single user instance of Team Foundation Server Express 11 Beta and run the XS VM instance without serious crashing? I know there are other Shared WebHost providers that can provide these features for me, but those hosting providers have the following disadvantages: They sometimes cost a lot of money after all of the "addons" are in place They probably don't provide the level of security and employee integrity that Microsoft can provide They don't provide the total control that an Azure VM seems to provide

• Can I convert an existing Firefox installation to ESR without a re-install?

  - by Iszi

  It took some jumping through hoops (including a mailing list subscription that I apparently didn't need) but I finally found where to download the Firefox ESR. This is great for fresh installs, but I was wondering if there's a way to simply convert existing installations to the ESR configuration without having to do a full install. As I understand it, the only difference between ESR and regular Firefox will be how they receive updates. After the new standard version of Firefox comes out, ESR releases will only receive critical security updates and bug fixes for the remainder of their support life. Newer versions of Firefox's standard build will have all the latest and greatest features, while ESR releases are meant to provide stability for environments that can't be expected to keep up with a new full version number change as often as Mozilla does them. In regular Firefox, the About screen shows that I am using the "release" update channel. Is switching to ESR really just a matter of switching the update channel? I presume this can be done in about:config by changing app.update.channel and probably also app.update.url. However, I don't know what these values should be for ESR or if anything else should be tweaked. So, is it possible to switch to ESR without a reinstall and, if so, how? (Note: While this question was written originally for Firefox 10, I expect any answers will apply to future ESR versions as well.)

• Windows 7 Aero theme's "greyed out" - no found fix

  - by Robsta

  Brand new machine that was working fine then randomly it changed the theme when I booted into a sort of "basic" theme (white task bar, no see through windows etc) I've done and attempted many fixes and I still don't understand why it doesn't work. I've tried these two solutions: "How to enable Windows 7 Aero Theme" and "Windows 7 Aero Themes Greyed out" These solutions included registy changes, stopping/starting services, and force starting the aero theme. The closest I got seems to be when I went into: Control panel (category view) Find and fix problems (System and Security) Display Aero Desktop Effects I follow through the wizard and let it do its thing and then I get an error window that pops up: Personalization - "This theme can't be applied to the desktop. Try clicking a diffrent theme." That's what I get from the wizard. What can I do? My drivers are all up to date, there are no viruses on the computer, directx is installed and updated, and the registry is all correct. EDIT: When I boot the computer, I get a notification stating that windows failed to communicate with the windows desktop services.

• Use of backreferences in fail2ban filters possible?

  - by Izzy

  From time to time, I see collections of suspect "File not found" errors in my Apache logs, basically using the pattern File does not exist: /var/www/file, referer: http://my.server.com/file In human terms: The file was not found, though it referenced here itself. A clear hacking attempt, as that's hardly possible (and the REQUEST_URIs often enough suggest the same). In my eyes a clear case for fail2ban – if I could get backreferences to work here: failregex = ^%(_apache_error_client)s File does not exist: /var/www(.+), referer: http://.+\1$ (Justin Case: above examples assume the DIRECTORY_ROOT of that webserver being /var/www) I googled for hours, searched the fail2ban wiki up and down – but nowhere I could find a statement concerning backreferences in its filters. Are they not supported, or did I do it the wrong way? Any hints how to make it work (except from "dirty hacks" like first sending the request to another fake url using mod-rewrite, and then catching on that (if anyone is interested, I can elaborate on that approach in an answer), or doing something similar using mod-security)? as an entire log line was requested: [Fri Nov 08 14:57:28 2013] [error] [client 50.67.234.213] File does not exist: /var/www/text/files.htm++++++++++++++++++++++++++Result:+using+proxy+27.34.142.47:9090;+no+post+sending+forms+are+found;, referer: http://www.myserver.com/text/files.htm++++++++++++++++++++++++++Result:+using+proxy+27.34.142.47:9090;+no+post+sending+forms+are+found; (sorry, logs were just switched, so this long candidate was the only one left currently; minor adjustments were made for privacy reasons)

• Access to File being restricted after Ubuntu crashed

  - by Tim

  My Ubuntu 8.10 crashed due to the overheating problem of the CPU when I am opening some directory and intend to do some file transfer under Nautilus. After reboot, under gnome, all the files cannot be removed, their properties cannot be viewed and they can only be opened, although all are still fine under terminal. I was wondering why is that and how can I fix it?

• is ksplice production ready?

  - by faultyserver

  I would be interested to hear the serverfault community's experiences with Ksplice in production. Quick blurb from wikipedia: Ksplice is a free and open source extension of the Linux kernel which allows system administrators to apply security patches to a running kernel without having to reboot the operating system. and Ksplice can, without restarting the kernel, apply any source code patch that only needs to modify the kernel code. Unlike other hot update systems, Ksplice takes as input only a unified diff and the original kernel source code, and it updates the running kernel correctly, with no further human assistance required. Additionally, taking advantage of Ksplice does not require any preparation before the system is originally booted (the running kernel does not need to have been specially compiled, for example). In order to generate an update, Ksplice must determine what code within the kernel has been changed by the source code patch. So a few questions: How has the stability been? any odd issues that you have encountered with its 'rebootless live patching' of the kernel? Kernel panics or horror stories? I have been running it on a few test systems and so far its been working as advertised, but I am interested in what other sysadmins experiences have been with Ksplice before going 'all in' and deploying this on our production servers. So, anybody using Kspice in production? update: hmm, not seeing any real activity on this question after a couple of hours (besides some kind upvotes and favs). Maybe to spark some activity I'll also ask a few more questions and see if we can get this discussion going... "If you are aware of Ksplice, is there a reason you are not using it?" "Do you feel its still too bleeding edge, unproven or untested?" "Does Ksplice not fit well within your current patch-management system?" "Do you hate having systems that have long (and secure) uptimes?" ;-)

• What's the issue with this Samba setup?

  - by Dan Nestor

  I asked this on superuser, but I realized that may be the wrong place. I am duplicating the question here, I hope this is allowed. I am trying to share a directory through samba. In smb.conf I have the following: [global] workgroup = WORKGROUP security = user passdb backend = tdbsam netbios name = <hostname> [share_name] path = </path/to/share> writable = yes valid users = <username> <username>, the user in question, is the owner of directory /path/to/share. Permissions on the directory are 755. If I try to connect from another computer, the connection attempt is unsuccessful (I assume it's an authentication error, because it re-prompts me for the password). The client requires a domain name for authentication, I tried both WORKGROUP and the hostname/netbios name of the samba server. Samba logs on the server have no mention of the failed connection attempt. Firewall on the server is down. What am I doing wrong? Update: have since run smbpasswd -a <username> and now I am getting a clear error message, "not enough permissions to view contents of share".

• mshtml.dll latest version for Internet Explorer 8, Windows XP Service Pack 3

  - by AllSolutions

  Many applications in my system (Internet Explorer 8, Yahoo Messenger, Skype 10) are crashing and error details shows module name mshtml.dll. I checked the version of mshtml.dll in system32 folder. It is 8.0.6001.19170. My Internet Explorer version is 8.0.6001.18702. I am not concerned about crash of IE, because I generally use Firefox, but how do I solve the crashes in other applications, which are due to mshtml.dll? I have moved to Windows XP Service Pack 3 (32 bit). I have tried to update Internet Explorer 8 (from Tools-Windows Update), but again it crashes. I can not migrate to IE 9, as it requires Vista or Windows 7. I have applied Cumulative Security update for IE8, which has this file name: IE8-WindowsXP-KB2618444-x86-ENU.exe I could not get much info from Microsoft sites or Google. I do not want to use Automatic Updates feature of Windows. Can somebody give the download links for mshtml.dll and any associated files, which I can replace in system32 folder? Thanks.

• hp DL380 G4 won't boot with disk plugged into front USB

  - by Kev

  We outgrew a few older external USB backup drives, and purchased WD My Passport 1 TB USB 3.0 drives to replace them. When they are plugged into the front of our G4, it will blink forever after the BIOS (which is current, BTW) and never boot, even though the USB disks are not "bootable" per se. Our old drives did not exhibit this behaviour (so I don't think it's this type of issue that I've read about other servers.) The old drives were USB 2.0, but this shouldn't make a difference, AFAICT--the specs say all of the G4's USB ports are the same, 2.0, anyway, so I'm not sure how one port would handle a USB 3.0 device better than another. If we plug the new drives in one of the back slots, it boots fine. What's the cause? My concern is that the front USB port, and possibly the motherboard, might be starting to die. (We are experiencing other strange issues with them, or were initially, like intermittent file permissions errors despite wide-open ACL on these local drives, but some serverfault users have me convinced they may be coincidental software/security related issues.)

• SQL SERVER 2005 with Windows 7 Problems

  - by azamsharp

  First of all I restored the database from other server and now all the stored procedures are named as [azamsharp].[usp_getlatestposts]. I think [azamsharp] is prefixed since it was the user on the original server. Now, on my local machine this does not run. I don't want the [azamsharp] prefix with all the stored procedures. Also, when I right click on the Sproc I cannot even see the properties option. I am running the SQL SERVER 2005 on Windows 7. UPDATE: The weird thing is that if I access the production database from my machine I can see the properties option. So, there is really something wrong with Windows 7 security. UPDATE 2: When I ran the orphan users stored procedure it showed two users "azamsharp" and "dbo1". I fixed the "azamsharp" user but "dbo1" is not getting fixed. When I run the following script: exec sp_change_users_login 'update_one', 'dbo1', 'dbo1' I get the following error: Msg 15291, Level 16, State 1, Procedure sp_change_users_login, Line 131 Terminating this procedure. The Login name 'dbo1' is absent or invalid.

• Issues regarding internet connectivity

  - by andySF

  Hello. My problem started when Yahoo Messenger stopped connecting. I've tried to see if Internet Explorer was working but will not load any page. The diagnostics of Internet Explorer says that is something wrong with my dns(using just ip of google or yahoo or my local webserver was not working). I use Windows 7 and at the moment i've had Internet Explorer 8 and after a lot of failing updates to ie9 I've successfully install the Romanian version of IE9(now i have ie8 after a system restore). Then I installed the service pack 1. I've done a lot of things and I will try to enumerate them, but my problem persists. Settings from Yahoo Messenger and Internet Explorer are OK. I've try to reset winsock and ip from netsh. I've scanned my pc with spybot, mallwarebytes, Trojan Remover(simplysup), Loaris Trojan Remover, Avast, Nod32, Kaspersky, Bitdefender,alot of registry cleaner including CCleaner and maybe others that I cannot remember now. I reset the registry permissions using subinacl. At a moment my files permissions was set jut to "trusted installer" and I've put the permission back to files and folders using the model of other windows 7 machine. I have try so many things that now i'm stuck in a loop using different security tools to check for problems. Oh, and my virtual machines are working just fine.(I'm using VirtualBox) Please Help. PS, Reinstalling Windows is not an option. Thank you!

• MacBook Pro and Backtrack 5R1 Configuration

  - by user119346

  I have a Macbook pro Quad core (2.2/8gb ram/750gb hdd). I have went through tons of forums on the Internet, but none of them seemed to be updated for the current Backtrack 5R1, or the question of getting it to correctly work on the MBP. Can anyone help? I don’t have a USB Dongle, and I want to be able to use the internal airport extreme wireless of the MBP to use BT 5R1. I have downloaded Backtrack 5R1 onto VMWare Fusion, and got it up and running, but to no avail. It keeps recognizing my card as a Ethernet connection. Kismac wont recognize the card either. So what I am asking for is this: The proper “download method.” for Backtrack 5R1 to my MacBook Pro. (YES I AM WILLING TO RE-DOWNLOAD BT 5R1). The Complete process from start to finish, UP TO DATE, from someone who has done this using an MBP Running Lion OSX. The proper tweaks, settings, or commands to get my airport extreme wireless card to work (it is BROADCOM 4331 I think). The wireless connection I need to use the tools on both Backtrack 5R1 and Kismac. I mainly need to test WEP cracking on my network for security. The difference between running BT 5R1 on VMWARE Fusion and running from downloading it directly to the MBP, if there is, How to download it directly to the MBP?

• I cannot access Windows Update at all

  - by Cardinal fang

  I have been unable to access the Windows update site for a couple of weeks now. I just get a message saying "Internet Explorer cannot display the webpage" and saying I have connection problems. Same thing is replicated with any other Microsoft site I try to access. The Automatic Updates also do not work. I can access every other wesbite I've surfed to. I've tried Googling the problem and based on what other site have suggested I have cleared my cache and temp files. I've scanning my hard drive with my antivirus in case I have a virus (nada). I've tried turning off my firewall and anti-virus (I run Zone Alarm). I've downloaded SpyBot and scanned my drive with that in case something was missed by Zone Alarm (again nada). Based on suggestions from the smart cookies on the Bad Science forum, I've used nslookup to check my translation isn't wonky (got all the info they said I should get). I've also tried navigating there directly using the IP address I was given (nope). I normally access the internet through a 3 mobile broadband connection, but have also tried connecting using a mate's wi-fi connection in case it was something on my mobile modem interferring. I run Windows XP SP3 with Internet Explorer 7 and Zone Alarm Internet Security Suite as my anti-virus/ firewall. Any suggestions?

• scalable yet doable small-medium office network

  - by Jared

  Hello, I'm studying up with both Microsoft and Cisco literature and I must say, my head is starting to get clustered up (pun intended). I've made a quick network diagram of a theoretical company... Company1 owns Company 2 and Company 3, which are all under separate rooms and networks, but must be able to share a few resources such as files or printers. Given the amount of info out there and best practices, I thought about posting here to get suggestions and see what would the pro's do. I can read and read all day and implement on my own, but if I dont get some outside input, how will I know if I'm doing something wrong, right? anyway, please take a look and see if this is an over-complicated network or a lackluster design for a small-medium company of about 35 people and lets say they will be double that number by end of the year... :) Using win2k3, esxi, windows xp. FCS - forefront client security, ACS - access control system, SPCWK - spiceworks, XCH - Exchange Im not allowed to post an image yet, so here's the link ---- GLIFFY IMAGE Flame suit is on just in case people get mad at me for making an "abomination". I'd really want to get the general overview properly before I dive into the more complicated things

• Undeliverable e-mail message from [email protected]

  - by QGfisher

  I am responsible for IT for a small charity and we have a problem with a few individuals who e-mail us on our hosted e-mail addresses. The individual is on btconnect and our server is also on BT broadband and using MSExchange. I understand that the message from [email protected] are generated by Exchange but can't tell whether this is a problem with our server (seems unlikely as most people send and receive e-mails perfectly well) or with the sender's server. I have copied a sample test message below and would be very grateful if somebody can explain what is causing this problem. I have * the personal details - hope that's acceptable but I don't want to compromise the individual's identity/security. ----- Original Message ----- From: "System Administrator" To: "****" <****.***@btconnect.com Sent: Tuesday, April 06, 2010 3:26 PM Subject: Undeliverable: Test Message Your message To: ***** Subject: Test Message Sent: Tue, 6 Apr 2010 15:25:59 +0100 did not reach the following recipient(s): ***@quiltersguild.org.uk on Tue, 6 Apr 2010 15:26:07 +0100 The e-mail account does not exist at the organization this message was sent to.

• Setting Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from newly mounted drives

  - by galacticninja

  How do I set Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from external hard drives and TrueCrypt-mounted volumes? I remember in Windows XP, I can set a percentage of total disk space that will automatically be used as storage capacity for deleted files by the Recycle Bin, and this will be applied to all external HDs or TC-mounted volumes. Windows 7 defaults to the 'Don't move files to the Recycle Bin. Remove files immediately when deleted' setting for newly mounted external HDs and TC mounted volumes. Since I am expecting deleted files to go to the Recycle Bin, sometimes this causes an 'Oops' when I delete files in external hard drives or TC mounted volumes, as Windows does not move deleted files to the Recycle Bin, but just deletes the files permanently. I have to remember to manually set a custom Recycle Bin storage space for each new drive that is mounted by Windows to avoid this issue. I only use and mount TrueCrypt file containers, not drives. I also don't mount TrueCrypt file containers as removable drives. ('Mount volume as removable medium' is unchecked in Mount Options.) In my $Recycle.Bin > Properties > Security settings, 'System' and 'Administrators' are already set to 'Full Control', while 'Users' only have 'Special Permissions' checked in gray. There are no other groups. I haven't changed or edited anything in these settings. I am using Windows 7 Ultimate.

• Change the Powershell $profile directory

  - by Swoogan

  I would like to know how to change my the location my $profile variable points to. PS H:\> $profile H:\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 H:\ is a network share, so when I create my profile file, and load powershell I get the following: Security Warning Run only scripts that you trust. While scripts from the Internet can be useful, this script can potentially harm your computer. Do you want to run H:\WindowsPowerShell\Microsoft.PowerShell_profile.ps1? [D] Do not run [R] Run once [S] Suspend [?] Help (default is "D"): According to Microsoft, the location of the $profile is determined by the %USERPROFILE% environment variable. This is not true: PS H:\> $env:userprofile C:\Users\username For example, I have an XP machine working how I want: PS H:\> $profile C:\Documents and Settings\username\My Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 PS H:\> $env:userprofile C:\Documents and Settings\username PS H:\> $env:homedrive H: PS H:\> $env:homepath \ Here's the same output from the Vista machine where the $profile points to the wrong place: PS H:\> $profile H:\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 PS H:\> $env:userprofile C:\Users\username PS H:\> $env:homedrive H: PS H:\> $env:homepath \ Since $profile isn't actually determined by %USERPROFILE% how do I change it? Clearly anything that involves changing the homedrive or homepath is not the solution I'm looking for.
