• Delay NTP Initialisation, Cisco 877W, IOS 12.4(24)T1

  - by Mike Insch

  I have a Cisco 877W which I'm using for my home ADSL connection (and as a refresher in Cisco IOS). I've got a working config in-place with my PPPoA connection coming online correctly, and VLANs and other settings configured as I want them, but I can't crack the NTP configuration. For NTP, I have the following defined ntp server 0.uk.pool.ntp.org source Dialer0 ntp server 1.uk.pool.ntp.org source Dialer0 ntp server 2.uk.pool.ntp.org source Dialer0 ntp server 3.uk.pool.ntp.org source Dialer0 This setup works fine when issued in Global Configuration Mode when the Dialer0 interface (ATM0.1) is up. The configuration fails at startup though: Translating "1.uk.pool.ntp.org"...domain server (208.67.222.222) (208.67.220.220) ntp server 1.uk.pool.ntp.org source Dialer0 ^ % Invalid input detected at "^" marker. This is repeated for the other servers defined. Obviously the DNS lookup for the server(s) fails because the DNS servers cannot be accessed because the external interface is not yet online. Is there a way to delay the NTP configuration until afte the Dialer0 interface is fully initialised? Can the NTP commands be triggered by the Line Protocol on the Dialer0 interface transitioning to the up state? Alternatively, can the NTP commands be delayed for 5 minutes after the router has finished initialising? Any advice, or pointers to useful documentation or examples gratefully received ...

• How to edit files directly on webdav in windows.

  - by phazei

  I have a webDAV setup with the cPanel webdisk. I can connect to it through NetHood and I can drag and drop files to/from there. What I can't do is simply edit any of the files directly. I need to copy it somewhere else, edit it, then copy it back. That's essentially what is needed with ftp, though smart clients will monitor the file, making it easier than webDAV in the current state I'm using it in. I was under the impression that webdav was supposed to let me work on the files as if it were a local drive. But nothing can actually open the files. How can I go about bringing more functionality around to it? Or is this as good as it gets? I have tried 'net use q:\ https://myserver.com:2078' and 'net use q:\ '\myserver.com@SSL:2078\' but neither work and only throws: "System error 67 has occurred. The network name cannot be found." I ultimately want to use TortiseSVN with the webDAV so I can have my working copy running on the server.

• samba share not on network after upgrading to Ubuntu 12.04LTS. [migrated]

  - by Sylvain Huard

  I just upgraded an old Ubuntu box to 12.04LTS (machine named A-Ubuntu). This is an upgrade not a format re-install. All the accounts and config were preserved. The basic setup is a local network with 2 Ubuntu machines (let say A-Ubuntu, B-Ubuntu) and a MAC (C-MAC). Before the upgrade, all of them could see each other by their names not only the IP address. The local network has a D-Link Router where everybody is connected with RJ-45 wired etherenet (not wi-fi). Since the A-Ubuntu upgrade, we can't see this machine name on the Network and its name is not on machine list in the D-Link router anymore. We can see it's IP address only. I can't access A-Ubuntu from the other two by its name but I can ping it with its address (192.168.0.109). From A-Ubuntu, I can connect and see the shared samba folders on B-Ubuntu and C-MAC. But from B-Ubuntu and C-MAc, I can't connect to A-Ubuntu. Correct me if I'm wrong but this tells me that Samba should be fine and the real problem is that A-Ubuntu does not advertise its name on the Network so the D-Link does not have it in its table so nobody else finds it. After a lot of googling, I see that it is the job of avahi and mdns to do so. Those packages are running, I checked multiple config files for samba, avahi, mdns to see as if it is like the examples on the WEB and also similar to what I find on the working B-Ubuntu machine. This is the same. I did multiple service restart with samba, avahi, remove the firewall to make sure it does not block the hostname broadcast. I rebooted multiple time to make sure the update I was making were effective. Still, Can't see the A-Ubuntu name on the network. Any idea what it can be?, Where to look next?

• IIS 7 - 403 Access Denied error on wwwroot trying to redirect to /owa

  - by cparker4486

  I'm trying to setup a redirect from http://mail.mydomain.com to https://mail.mydomain.com/owa. I've been unsuccessful in doing this by using IIS's HTTP Redirect so I looked to other options. The one I settled on is to create a default document in the wwwroot folder to handle the redirect. I created a file called index.aspx (and added index.aspx to the list of default documents) and put the following code in it: <script runat="server"> private void Page_Load(object sender, System.EventArgs e) { Response.Status = "301 Moved Permanently"; Response.AddHeader("Location","https://mail.mydomain.com/owa"); } </script> Instead of getting a redirect I get: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. I've been trying to find an answer to this but have been unsuccessful so far. One thing I did try was to add the Everyone group to wwwroot with read access. No change. The AppPool for Default Web Site is DefaultAppPool and the Identity is ApplicationPoolIdentity. (I don't know what these things are but maybe knowing this will help you.) Thanks!

• Dell XPS m1530 system cannot boot need 130w or greater

  - by KPS

  I have a Dell XPS M1530 and I lost my old AC adapter but ordered a new one. For the longest time it always had a battery charge so I was able to boot into the OS but now it is completely dead. I have a generic charger that slowly charged the laptop when it was in the OS but does not when the computer is off. When I boot up I get the following error: The AC power adapter type cannot be determined. The system can only boot with a 130 W power adapter or greater. Strike F1 key to shutdown. I cannot even enter the BIOs setup screen or boot menu, is there a way around this? I heard from the local tech that Dell has a special feature to boot from thumb drive before getting past the initial logo. I am doing my best to avoid purchasing a new charger since it worked just fine when the OS was running, I am hoping to get this thing going. Is there a way to charge the battery externally? Thanks in advance for any help!

• JBoss7 load balancing with mod_proxy_balancer - session not working

  - by Phil P.

  I am trying to set up mod_proxy_balancer for routing requests to 2 jboss7-servers. For the time being I am testing this setup on my local machine, using following config in httpd.conf: ProxyRequests Off <Proxy \*> Order deny,allow Deny from all </Proxy> ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid scolonpathdelim=On <Proxy balancer://mycluster> BalancerMember http://localhost:8080 route=node1 BalancerMember http://localhost:8081 route=node2 Order allow,deny Allow from all </Proxy> and in the standalone.xml file of each jboss I have defined the jvmRoute system property: <system-properties> <property name="jvmRoute" value="node1"/> </system-properties> At http:// localhost/myapp the application is accessible but the java-session is not build up correctly. Consequently the authentication is not working. The funny thing is, that everything is working if I turn off one JBoss-instance. As I have tried a couple of settings already, I am thankful for any further suggestions.

• Can't install SB750 RAID drivers in Windows 7 for two additional storage drives

  - by jf46

  Mobo: ASUS M4A79XTD, 790X/SB750 OS: Windows 7 x64 I currently have SATA 1-4 set to RAID and SATA 5-6 set to IDE. I have an SSD connected to SATA5 with Windows 7 installed on it, and that works fine. I also have configured a RAID 1 array of two 1TB HDDs, connected to SATA 1 and 2. These don't show up in Windows, and I'm having trouble getting the RAID driver installed. I even tried booting from the Windows DVD and repairing or installing Windows, but when I navigated to the relevant .sys files on my motherboard's driver CD, Windows setup told me that the files in question weren't relevant to my hardware. To be clear: I'm not trying to install Windows on a RAID. I have Windows installed on a separate disk on a separate SATA controller. I just want to get the SB750 RAID drivers installed so that the Windows disk utility can see my RAID 1 array, which is composed of two other disks. Do I need to wipe my SSD and reinstall Windows to get the RAID driver installed? That seems kind of ridiculous, and given what I described above, I'm not even sure it would work. Any help or guidance would be appreciated - thanks! Edit: Also, I've copied the driver files from the mobo CD into system32 and rebooted, no luck. Then I changed HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV\Start from 3 to 0, and that didn't work either.

• Problems installing Adobe Premiere Elements 8 Content features

  - by Walt Maken

  I recently purchased Adobe Photoshop & Premiere Elements 8. Photoshop Elements 8 installed fine, along with the additional material available via internet download. Premiere Elements 8 installed ok from the DVD. During the Premiere Elements 8 startup process the following message appears: A reduced set of content (Instant Movie Themes, Title and Menu Templates,etc) has been installed. To install the full content set, please insert your Content DVD and run Setup.exe. If you do not have a Content DVD please visit http://www.adobe.com/go/pre_additional_downloads to download the content installer. Since I didn't have the Content DVD, I did the download, which took nearly 12 hours. The extract appeared to complete at 100%, but then immediately gave the error message "A problem occurred while extracting some files. Check available space on your computer and the write privileges on the destination folder." Why would it show this error message if it had completed the extract process 100%? What step(s) do I take now to have Content installed? Do I need to go thru the 12 hour download again or, hopefully, is there something I can do that will make it unnecessary to download again?

• What service do you use for music on hold?

  - by Russ Warren

  This may not be a sysadmin question for some, but it is definitely a hurdle I have to jump as the sysadmin for my company. We recently rolled-out a company wide VoiP system (Switchvox, to be exact) that has come preloaded with some royalty-free music on hold. Our customers have been complaining that the music on hold sounds like "funeral music." This may be the case (although I wouldn't want it played at my funeral), but it is all we have and we aren't willing to be sued over using music that isn't properly licensed. So, that brings me to the question asked in the title -- what and/or how do you provide decent music on hold? I'm assuming many people here use a PBX that allows customized music, so this has to apply to many of you. We've been looking at some sites that allow you to download royalty-free music for a one-time fee, but the music seems...lame. Something like a one-year subscription from ibaudio.com seems to be the best bet so far. Have you been able to discover something a little more mainstream for a decent licensing fee? Thank you. EDIT: Our PBX allows the playback of MP3 and OGG files, but does not allow streaming of a live audio source, Internet-based or otherwise. It also does not allow the use of a "line-in" source such as a CD player or radio. Don't let this stop you from sharing your setup, though. I'm interested in hearing what everyone uses!

• Pinging an external server through OpenVPN tunnel doesn’t work

  - by qdii

  I have an OpenVPN server and a client, and I want to use this tunnel to access not only 10.0.8.0/24 but the whole internet. So far, pinging the server from the client through the tun0 interface works, and vice versa. However, pinging www.google.com from the client through tun0 doesn’t work (all packets are lost). I figured that I should configure the server so that any packet coming from tun0 in destination of the internet be forwarded, so I came up with this iptables config line: interface_connecting_to_the_internet='eth0' interface_openvpn='tun0' internet_ip_address=`ifconfig "$interface_connecting_to_the_internet" | sed -n s'/.*inet \([0-9.]*\).*/\1/p'` iptables -t nat -A POSTROUTING -o "${interface_connecting_to_the_internet}" -j SNAT --to-source "${internet_ip_address}" echo '1' > /proc/sys/net/ipv4/ip_forward Yet, this doesn’t work, the packets are still lost and I am wondering what could possibly be wrong with my setup. Some details: ip route gives on the server: default via 176.31.127.254 dev eth0 metric 3 10.8.0.0/24 via 10.8.0.2 dev tun0 10.8.0.2 dev tun0 proto kernel scope link src 10.8.0.1 127.0.0.0/8 via 127.0.0.1 dev lo 176.31.127.0/24 dev eth0 proto kernel scope link src 176.31.127.109 ip route gives on the client: default via 192.168.1.1 dev wlan0 proto static 10.8.0.1 via 10.8.0.5 dev tun0 10.8.0.5 dev tun0 proto kernel scope link src 10.8.0.6 127.0.0.0/8 via 127.0.0.1 dev lo scope link 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.109 client uses wifi adapter wlan0 and TUN adapter tun0. server uses ethernet adapter eth0 and TUN adapter tun0. the VPN spans on 10.0.8.0/24 both client and linux are using Linux 3.6.1.

• Emails going to Junk for Hotmail recipients

  - by David George

  We send daily mass emails to our customers (~30,000+ emails per day). We have problems with Hotmail users receiving our emails. Sometimes the email goes to the Junk folder, but often it will got to their inbox, but the content is blocked so the user sees a message saying "This email was blocked and may be dangerous". If an email is sent to GMAIL it is usually not blocked, but it does show up as from "Uknown" instead of the company. Please be advised I've done the following: 1. No RBLs Checked on - http://multirbl.valli.org/ 2. We do have SPF records published 3. We do have reverse DNS setup 4.

• OSX Server 10.5 - Cannot log into Workgroup Manager - diradmin password is correct

  - by Mister IT Guru

  I've got a setup where I am trying to rescue a broken AD. We can no longer authenticate on the Workgroup manager, with passwords being rejected all the time - even though it is correct. I can connect using the workgroup manager on another server and I get the user list as expected, but when I click the padlock to make changes, I get the following screen: The problem is, I know the password is correct, I just used it to connect to the server in the first place. I can log into the server using the local admin, and services such as AFP, VPN and SMB continue to serve users. I have about 300 or so users on this server, and I would very much like to avoid having a rebuild. As there is much configuration that has been done without my knowledge (it's a client machine), I'd like to attempt to fix it, and then create another server and migration OD off this broken machine, then decommission it "gently". Ultimately this would mean no disruption of services. What I'd like it some tips as to how to fix the problem with authenticating to make changes in the work group manager, and maintenance on open directory in general. Thanks

• Xvnc4 started from xinetd only displays empty gray X screen

  - by Scott Thomason

  I'm attempting to setup an Ubuntu 10.10 box so that anyone can connect to port 5900 and be greeted by the gdm login manager. To do so, I added a vnc entry in /etc/services and I am starting Xvnc4 using this xinetd config file: service vnc { protocol = tcp socket_type = stream wait = no user = nobody server = /usr/bin/Xvnc server_args = -geometry 1000x700 -depth 24 -broadcast -inetd -once -securitytypes None } This kind of works...I can start multiple sessions all to port 5900, and I get an X screen. The problem is that I only get an empty, gray X screen with no applications started. I know when you run vncserver from the command line it will look to your ~/.vnc/ directory for your passwd and xstartup files, and I think what I want to do is put "gnome-session" into the xstart file. However, which xstartup file? The running user is "nobody" who obviously doesn't have a ~/.vnc/ directory. I tried a /root/.vnc/xstartup file and a ~scott/.vnc/xstartup file and it doesn't look like they were even read. I changed the xinetd vnc service so that it would "strace" Xvnc4. I looked thru all the "open" lines and didn't get a clue as to what file it was trying to read for xstart. Can anyone help? I just want a terminal server where the user is presented with a gdm login screen.

• Best practices for settings for Oracle database creation

  - by Gary

  When installing an Oracle Database, what non-default settings would you normally apply (or consider applying) ? I'm not after hardware dependent setting (eg memory allocation) or file locations, but more general items. Similarly anything that is a particular requirement for a specific application rather than generally applicable isn't really useful. Do you separate out code/API schemas (PL/SQL owners) from data schemes (table owners) ? Do you use default or non-default roles, and if the latter, do you password protect the role ? I'm also interested in whether there's any places where you do a REVOKE of a GRANT that is installed by default. That may be version dependent as 11g seems more locked down for its default install. These are ones I used in a recent setup. I'd like to know whether I missed anything or where you disagree (and why). Database Parameters Auditing (AUDIT_TRAIL to DB and AUDIT_SYS_OPERATIONS to YES) DB_BLOCK_CHECKSUM and DB_BLOCK_CHECKING (both to FULL) GLOBAL_NAMES to true OPEN_LINKS to 0 (did not expect them to be used in this environment) Character set - AL32UTF8 Profiles I created an amended password verify function that used the apex dictionary table (FLOWS_030000.wwv_flow_dictionary$) as an extra check to prevent simple passwords.

• Cannot send email outside of network using Postfix

  - by infmz

  I've set up an Ubuntu server with Request Tracker following this guide (the section about inbound mail would be relevant). However, while I'm able to send mail to other users within the network/domain, I cannot seem to reach beyond - such as my personal accounts etc. Now I have no idea what is causing this, I thought that all it takes is for the system to fetch mail through our exchange server and be able to deliver in the same way. However, that hasn't been the case. I have found another server setup in a similar fashion (CentOS 5, Request Tracker but using Sendmail), however it is a dated server and whoever's built it has kindly left no documentation on how it works, making it a pain to use that as a reference system! :) At one point, I was told I need to set up a relay between the local server's email add and our AD server but this didn't seem to work. Sorry, I know next to nothing about mailservers, my colleagues nothing about Linux so it's a hard one for me. Thank you!

• Why is the link between my switch and my router always negotiating half-duplex mode?

  - by Massimo

  I have a Cisco 2950 switch which has one of its ports connected to an Internet router provided by my ISP; I have no access to the router configuration, but I manage the switch. If I leave all switch ports with their default setup (auto-negotiation of speed and duplex mode), this link always connects at 100 MBit/s, but in half-duplex mode. I've tried replacing the cable, and also moving the link to another switch port: the result is always the same. A different device connected to the same port (or to any switch port, really) shows no problem at all. It could be guesed that someone configured the router to only connect in half-duplex mode... BUT, here's the catch: if I manually force the switch port to full-duplex mode (duplex full in the interface configuration), the link goes up, stays up and is completely stable. So: The connection is not forced to half-duplex mode by the router, otherwise it would not connect at all if I force the switch end to full-duplex. There is no actual link problem, otherwise the full-duplex connection would not go up or would at least show some errors. But if I leave the port free to auto-negotiate, it always connects in half-duplex mode. Why?

• Ubuntu Server: Networking fails with MODPROBE option in /etc/network/interfaces ... ??

  - by neezer

  For some reason (which I haven't been able to determine yet), yesterday morning the networking service on our web server (running Ubuntu 8.04.2 LTS -- hardy) wouldn't start, and our website went down. I noticed the following error message when trying to restart it: * Reconfiguring network interfaces... /etc/network/interfaces:6: option with empty value ifup: couldn't read interfaces file "/etc/network/interfaces" ...fail! Line 6 in the /etc/network/interfaces file concerned a MODPROBE command, which (I believe) loaded in the ip_conntrack_ftp module so that I could use PASV on my FTP server (vsftpd): (breaking modprobe commands commented out below) # Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or # /usr/share/doc/ifupdown/examples for more information. # The loopback network interface auto lo iface lo inet loopback #MODPROBE=/sbin/modprobe #$MODPROBE ip_conntrack_ftp pre-up iptables-restore < /etc/iptables.up.rules # The primary network interface # Uncomment this and configure after the system has booted for the first time auto eth0 iface eth0 inet static address xxx.xxx.xxx.xxx netmask 255.255.255.0 gateway xxx.xxx.xxx.1 dns-nameservers xxx.xxx.xxx.4 xxx.xxx.xxx.5 I've verified that there is a file in /sbin called modprobe. Like I said earlier, this setup had been working flawlessly until yesterday morning (though my bosses say that the site actually went down the previous night at 11 PM EST). Can anyone shed some light on (A) why this broke, and (B) how can I re-enable the ip_conntrack_ftp module?

• Multiple PHP SAPI configuration

  - by DTest

  I'm trying to build PHP for use as an apache shared module --with-apxs2 but also with the 'php-cgi' binary (fastcgi) on Mac OSX 10.6. I'm using this ./configure : /configure --prefix=/usr/local/PHP \ --with-apxs2=/usr/local/apache/bin/apxs \ --disable-ipv6 \ --enable-cgi \ --with-curl \ --with-mysqli=/usr/local/mysql/bin/mysql_config \ --with-openssl=/usr \ --enable-ftp \ --enable-shared \ --enable-soap \ --enable-sockets \ --enable-zip \ --with-zlib-dir It builds the apache php5.so module just fine, but in /usr/local/PHP/bin, there is no php-cgi file. If I build it without the --with-apxs2 option (and indeed, I don't even need the --enable-cgi option) the php-cgi file gets built with no problems. Background on my setup: PHP 5.3.4, Apache 2.2.14, Mac OSX 10.6, Tomcat with JavaBridge (which is why I need the php-cgi file) Without the apxs2 option, /usr/local/php/bin/php -v produces: PHP 5.3.4 (cli) (built: Dec 21 2010 21:35:14) Copyright (c) 1997-2010 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies and /usr/local/php/bin/php-cgi -v produces: PHP 5.3.4 (cgi-fcgi) (built: Dec 21 2010 21:35:12) Copyright (c) 1997-2010 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies My question is, what am I not understanding with php SAPIs that won't allow the building of the two modules at the same time? Also, can I build it --with-apxs2 the first time, then make clean and rebuild in the same PHP directory /usr/local/php for the php files without issue?

• scanner no longer working windows 7

  - by Sackling

  I have a windows 7 64 pro machine that for some reason no longer works with a brother all in one printer/scanner, when I try to scan. This happened seemingly out of nowhere. Printing still works. When I try to scan from photoshop, photoshop crashes. When I try to scan from device manager (which takes a really long time to access the printer) I get an error saying: "operation could not be completed. (error 0x00000015). the device is not ready. I tried uninstalling/reinstalling the printer and drivers. I have also run the brother driver cleaner and then reinstalled and get the same results every time. I had access to another HP all in one. And very strangely When I setup this new printer I have a similar issue that happens. I am able to print but when I try to scan from the HP tool nothing pops up. So my thoughts are it is something to do with the twain driver? But I don't know what to do or check. Any help is appreciated.

• Linux Sound Drivers - Recompiling kernel with ehcd-hcd module

  - by jhome

  I just installed Linux Mint and I am trying to get my usb soundcard to work. I am completely new to Linux so I have only been learning about all the important parts of the OS this afternoon. No one I know has compiled kernel so I can't ask anyone. I am following instructions on this site: http://wiki.ubuntuusers.de/Benutzer/BigMc#Final-setup-of-US-122L-US-144 "Recompile your Kernel with ehcd-hcd as a module: Instructions for Ubuntu (german) Change "Device Drivers - USB support - EHCI HCD (USB 2.0) support)" to "M" when configuring. Make sure you also install the kernel headers." I know how to do any of these processes. Someone mentioned a package manager. Is recompiling basically in layman's terms reinstallation? Where do I go to the change device drivers? Cheers Edit: I am attempting to be able to use my Tascam US-144 on Linux Mint. Apparently, to use it properly it has to regress to functionality of a former unit (US-122), so according to the instructions a USB port has to be USB 1.0, rather than USB 2.0. I've tried using that ndis** programme for wireless drivers but with no success.

• Howto: SaaS / PHP Application / Tenants / Security

  - by Ben Fransen

  Hi all, Being completely new in the webhostingcorner I have a few questions on how to implement/setup a webserver for a SaaS application. I'm about to rent my own server for a new product (CMS) I'm launching in two months. Developing the system wasn't that much of wild ride to me, but a correct way to implement it, is. So lets say this is my situation: I want to host 10 websites for 8 clients. There are 6 single sites, and two clients have two websites they can manage with my software. The CMS must be placed on the server too, all clients are connecting to 1 system The database must be placed Depending on the contract a client makes, the client gets some storage. How to measure the used storage over the DB, FileSystem and email Clients may not, in any case be able to somehow get outside their directory, but from the CMS directory the CMS must be able to create files and dirs in a clients directory (for templates, imagegalleries, widgets, etc, etc). I was thinking about something like a dirstructure like this: ./CMS/ [all CMS files] ./Websites/*/ [all websites] My hostingprovider will install updates to the os (CentOS, latest) and the admin panel (Direct Admin). Is there anybody with experience on this topic? Or do you have some thoughts about it? please join the conversation since I'm completely new to this. Ben

• How to Refresh or Reset Windows 8 without the System Reserved partition?

  - by Karan

  The article Refresh and reset your PC mentions exactly what happens during the refresh and reset operations in Windows 8: Refresh The PC boots into Windows RE. Windows RE scans the hard drive for your data, settings, and apps, and puts them aside (on the same drive). Windows RE installs a fresh copy of Windows. Windows RE restores the data, settings, and apps it has set aside into the newly installed copy of Windows. The PC restarts into the newly installed copy of Windows. Reset The PC boots into the Windows Recovery Environment (Windows RE). Windows RE erases and formats the hard drive partitions on which Windows and personal data reside. Windows RE installs a fresh copy of Windows. The PC restarts into the newly installed copy of Windows. It is my understanding that Windows RE (Recovery Environment) is included as part of the System Reserved partition created by default on the first hard disk. The size of this partition has gone up to 350 MB from the 100 MB it used to be in Vista/Windows 7, no doubt as a result of adding these features. Now we have already discussed how to skip the creation of this System Reserved partition during Setup. Basically, the same techniques that used to work with Windows 7 work with Windows 8 as well. What I want to know is, what will be the exact repercussions of not having the System Reserved partition in place? I assume Troubleshoot / Advanced options should still be available as before: But what about the Troubleshoot menu itself? Will the Refresh and Reset options disappear? Will they remain but be unavailable? Or possibly they will throw an error if selected? Also, will it be possible to access and successfully execute these options if installation media is available? Anything else that might be affected?
