  • Win 7 crashes, PC reboots and says "Hard drive 0 not found" until I turn if off and on again

    - by Danny T.
    I recently made the move from Windows XP to Windows 7. Since then, when my computer is on for a few hours it always ends up rebooting without warning. Then the BIOS won't recognize my hard drive (hard drive 0 not found). If I turn off my computer and then on again, it boots normally. Some details: Dell Dimension 9150 Windows 7 I updated the BIOS I updated all system drivers with the latest version from Dell (SATA, Chipset, etc.) Other drivers updated too (Graphic card, sound, etc.) There is one thing that I tried after some Googling: I turned off the DMA access to the drives, but it's still rebooting after a few hours. Any clue? UPDATE 2010/12/13 Here are the events from the Event Log for today, from when I turned the computer on until it crashed: 19:17 - Error - ID 10016 - DistributedCom 20:06 - Error - ID 1008 - Customer Improvement Program (could not send data to Microsoft) 21:48 - Critical - ID 41 - Kernel-Power (System was restarted without proper shutdown) 21:48 - Error - ID 6008 - EventLog (Previous system down was not planned) 21:48 - Error - ID 1101 - EventLog (Audit Event ignored) 21:49 - Error - ID 10016 - DistributedCom Both DistributedCom events have a description along these lines (translated from French): The authorisation parameters specific to the application are not allowing Local Execeution for the COM server application with the CLSID {C97FCC79-E628-407D-AE68-A06AD6D8B4D1} and the APPID {344ED43D-D086-4961-86A6-1106F4ACAD9B} to the SID AUTHORITY NT\User System (S-1-5-18) from the address LocalHost (LRPC usage).

  • Give Access to a Subdirectory Without Giving Access to Parent Directories

    - by allquixotic
    I have a scenario involving a Windows file server where the "owner" wants to dole out permissions to a group of users of the following sort: \\server\dir1\dir2\dir3: Read & Execute and Write \\server\dir1\dir2: No permissions. \\server\dir1: No permissions. \\server: Read & Execute To my understanding, it is not possible to do this because Read & Execute permission must be granted to all the parent directories in a directory chain in order for the operating system to be able to "see" the child directories and get to them. Without this permission, you can't even obtain the security context token when trying to access the nested directory, even if you have full access to the subdirectory. We are looking for ways to get around this, without moving the data from \\server\dir1\dir2\dir3 to \\server\dir4. One workaround I thought of, but which I am not sure if it will work, is creating some sort of link or junction \\server\dir4 which is a reference to \\server\dir1\dir2\dir3. I am not sure which of the available options (if any) would work for this purpose if the user does not have Read & Execute permission on \\server\dir1\dir2 or \\server\dir1, but as far as I know, the options are these: NTFS Symbolic Link, Junction, Hard Link. So the questions: Are any of these methods suitable to accomplish my goal? Are there any other methods of linking or indirectly referencing a directory, which I haven't listed above, which might be suitable? Are there any direct solutions that don't involve granting Read & Execute to \\server\dir1 or \\server\dir2 but still allowing access to \\server\dir1\dir2\dir3?

  • "What happens?" server performance monitor

    - by AlexAtNet
    Hello! After reviewing some thread about server monitoring software I end up with a simple question: Which of the server monitoring tools should I use for automatic detection of "abnormal" situations with recommendations on how to fix them? I look for software that checks the system performance after installation and calculate some average load values (memory, CPU, etc). And when something happens (CPU load is increased to 20%) then it tries to detect a reason for this. If it is apache, it should check for access logs. If mysql, it should check mysql logs and tell me what happens. It this is because some user decodes a lot of images, I'd like to know which command is executed, when and user name. The same for disk usage, memory, number of processes, threads and so on. Ideally, this software should periodically checks the system and report problems: errors in PHP error log, outdated packages, security vulnerabilities. In other word I'm looking a software that will keep my simple Debian/Apache/PHP/MySQL server without forcing me to monitor the charts every day. I hope that such program exists. Thanks, Alex

  • How do I set up an email server that automatically maintains a list of previous recipients?

    - by hsivonen
    I want to set up an email server with the following characteristics. What software (besides bogofilter and clamav that I'm naming) should I use and what HOWTOs should I read? The server should run some flavor of Linux that's as low-maintenance as possible and self-updates for security patches in a timely fashion. (Debian stable?) When email is sent, all the recipients are stored in the list of previous recipients maintained by the server. Scan incoming messages with clamav and treat as spam if it contains viruses. When email arrives (if it passed clamav), if the sender is on the list of previous recipients, bypass spam filter. If the List-Id header names a mailing list on a manually maintained list of known-clean mailing lists, bypass spam filter and deliver into a mailbox depending on the mailing list name. Email that wasn't from previous recipients, manually white listed domains or mailing lists gets filtered by bogofilter. Spam goes into a spam mailbox. Email considered to be ham should automatically be fed to bogofilter training as ham. Email considered to be spam (incl. messages with viruses) should be automatically fed to bogofilter training as spam. There should be mailboxes for false ham and false spam that an IMAP client can move email into so that the server retrains bogofilter appropriately. Email sending requires SMTP over SSL. Email reading requires IMAPS. Should I also want to use SpamAssassin in addition to bogofilter?

  • Exchange 2010 - Certificate error on internal Outlook 2013 connections

    - by Lorenz Meyer
    I have an Exchange 2010 and Outlook 2003. The exchange server has a wildcard SSL certificate installed *.domain.com, (for use with autodiscover.domain.com and mail.domain.com). The local fqdn of the Exchange server is exch.domain.local. With this configuration there is no problem. Now I started upgrading all Outlook 2003 to Outlook 2013, and I start to get consistently a certificate error in Outlook : The Name on the security certificate is invalid or does not match the name of the site I understand why I get that error: Outlook 2013 is connecting to exch.domain.local while the certificate is for *.domain.com. I was ready to buy a SAN (Subject Alternate Names) Certificate, that contains the three domains exch.domain.local, mail.domain.com, autodiscover.domain.com. But there is a hindrance: the certificate provider (in my case Godaddy) requires that the domain is validated as being our property. Now it is not possible for an internal domain that is not accessible from the internet. So this turns out not to be an option. Create self-signed SAN certificate with an Enterprise CA is an other option that is barely viable: There would be certificate error with every access to webmail, and I had to install the certificate on all Outlook clients. What is a recommended viable solution ? Is it possible to disable certificate checking in Outlook ? Or how could I change the Exchange server configuration so that the public domain name is used for all connections ? Or is there another solution I'm not thinking of ? Any advice is welcome.

  • Ubuntu in failed state after upgrade from 10.04 to 10.10 - How to recover?

    - by Harvey
    I was running Ubuntu 10.04 and attempted to upgrade to 10.10. I have a really slow connection (DSL 128kbits/sec) and copying the upgrade files took about 26 hours. I of course let it run unattended. When I came back, I notice the following 3 dlgs: 1. Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg -- configure -a). 2. gpk-update-icon Distribution upgrades available maverick 10.10 (stable) [more information] [Do no show this again] [Cancel] [Ok] 3. gpk-update-icon Security updates available The following important updates are available for your computer: libwebkit-1.0-2-dbg - Web content engine library for Gtk+ - Debugging symbols libcupsimage2 - Common UNIX Printing System(tm) - Raster image library ... What is the best response to all of this? I went through something similar in an attempted network upgrade from 8.04 to 10.04 and had to reload the unbootable machine fresh from distribution media (all data was lost). I'd like to avoid that here. I have not yet responded to the dialogs, and want to make sure the system is still bootable and not lose my data this time.

  • Offline productivity

    - by Frank Meulenaar
    On some days I'm commuting 2hs (oneway) in the train. I don't have any mobile internet nor is there always WiFi service in the train. Because of security reasons I can't do any work in the train so I'm trying to work on my geek time. I'm looking for general solutions on how to do this (I'm on FireFox/Windows but I don't think it matters) Email works perfectly with gmail offline. It syncs directly when online and remembers complicated stuff. So far I used the ScrapBook plugin to store an website. It works good, but I have to download my favorite news page every day again - I want it to sync as soon as possible. It would even be more awesome if I could click a page on my desktop and my laptop would sync as soon as it has the chance. (edit: maybe the autosave plugin for scrapbook can do this) Similarily, I use the Downloadhelper plugin to download youtube vids, but I'd like something that automatically downloads videos from a given channel. Any tips are welcome. So far my early morning schedule is: wake up, power on laptop, make coffee, power off laptop and leave within 10 minutes (enough time for GMail to sync) but I can imagine a system where my laptop stays on during the night (or boots before I wake (and makes me coffee :])).

  • How to view / enumerate / obtain a list of all effective rights / permissions on an Active Directory object?

    - by Laura
    I am new to Server Fault and was hoping to find an answer to a question that I have been struggling with for the past week or so. I have been recently asked by my management to furnish a list of all the effective rights / permissions delegated on the Active Directory object for our Domain Admins group. I initially figured I'd use the Effective Permissions Tab in Active Directory Users and Computers but had two problems with it. The first was that it doesn't seem very accurate and the second was that it requires me to enter the name of a specific user, and it only shows me what it figures are effective permissions for that user. Now, we have more than a 1000 users in our environment so there's no way I can possibly enter 1000 user names one by one. Plus, there is no way to export that information either. I also looked at dsacls from MS but it doesn't do effective permissions. Someone pointed me to a tool called ADUCAdmin but that seems to falsely claim to do effective permissions. Could someone kindly help me find a way to obtain this listing? Basically, I need to generate a list of all the modify effective permissions granted on the Domain Admins group object along with the list of all the admins to which these permissions are granted. In case it helps, I don't need a fancy listing - simple text / CSV output would be enough I would be grateful for any assistance since this is time and security sensitive for us.

  • "Access is Denied" when executing application from Command Prompt

    - by xpda
    Today when I tried to run an old DOS utility from the XP Command prompt, I got the message "Access is Denied." Then I found that most of the DOS utilities would not run, even though I have "full control" over them. They worked just fine a few weeks ago, and I have not made any OS changes other than Windows Upgrades. Then I tried running edlin.exe and edit.com from the Windows\system32 folder. Same result - "Access is Denied." I tried running these applications from Windows Explorer and got the message "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I am logged in as a member of Administrators and have full control over these files. I tried logging in as THE Administrator, with no change. I checked the security settings on the files, and have full control over all of them. I have tried copying the files to different drives, booting in safe mode, and running without antivirus and firewall, all with no change. Does anybody know what could cause this?

  • Samba access works with IP address only

    - by Sebastian Rittau
    I added a Debian etch host (hostname: webserver, IP address: 192.168.101.2) running Samba to a Windows network with a Windows 2003 PDC (IP address 192.168.101.3). The Samba server exports a public guest share, called "Intranet". The server shows up fine in the network, but trying to click on it produces an error dialog, stating I don't have the necessary permissions. So does entering \webserver manually and using \webserver\internet states that the path does not exist. Interestingly, accessing the share by IP address (\192.168.101.2 or \192.168.101.2\intranet) works fine. DNS is configured correctly, and "smbclient //webserver/intranet" on another Linux client works fine. One complicating issue is that the webserver is only a VMware virtual machine running on PDC server. Here is our smb.conf: [global] workgroup = Foobar server string = Webserver wins support = yes ; commenting out these wins server = 192.168.101.3 ; two lines has no effect dns proxy = no guest account = nobody [... snipped some unrelated bits, like logging ...] security = share [... snipped some password-related things ...] domain master = no [intranet] comment = Intranet path = /srv/webserver/contents browseable = yes guest ok = yes guest only = yes read only = yes create mask = 0775 directory mask = 0775

  • What is going on when I can't access an SMB server share (not accessible error) until I run cmdkey to delete the credential?

    - by Warren P
    I have a network connection share issue. The first connection works, and seems to stay connected for at least a few hours. However, after each time my windows 7 PC reboots, it can no longer form a network connection to the shared folder, nor browse to it, until I not only unmap and remap the mapped drive, but also, I have to use cmdkey to delete the stored credentials like this: cmdkey /delete:Domain:target=HOSTNAME My work PC is on a domain, and I am not the IT administrator, but I'm curious if there is anything I can do to investigate this issue. Any settings in registry or group policy that I could examine to see why the first connection works, but each subsequent attempt (once a stored credential exists) to browse or use the connection, fails with a connection error saying it is "not accessible", like this: I do not even get any error until at least several minutes go by. THe first thing I see is a window frozen and empty, and then I get this error: This has happened when connecting to a share on a DROBO device, and on a share which is not on the domain, but which was a Microsoft Home Server. I wonder if there's something broken in WIndows 7 professional with regards to connecting to non-domain shares when an active directory domain controller exists, and a particular workstation is joined to a domain? The problem only occurs if I click "remember credentials". It is not fixed by any amount of working with net use. Usingcmdkey to delete all stored credentials for the host is the only way to get back in, and it affects all non-domain shared folders. Update I'm hoping there are some registry locations I could check that could be misconfigured in some way that might explain why SMB/CIFS stored credentials for non-domain systems seem to be auto-invalidated in this weird way. Knowing how whacko Microsoft Windows domain and security handling is sometimes, this could be some kind of stupid "feature".

  • saving and searching encrypted mail

    - by user53616
    I often send and receive gpg-encrypted mail. At the moment I use thunderbird + enigmail (in linux) to do that. As far as I know there is no way in thunderbird to find all encrypted messages which bodies contain particular keywords. There also seems to be no option to save encrypted mails decrypted (so they would be searchable). However for me it is important to be able to search old encrypted mails. So my question is: Is there a way in linux to save incoming mails automatically decrypted in my inbox and save outgoing encrypted mail decrypted in the send folder? Both times adding a line to the body which remarks that the mail was encrypted. It could be another email client for linux that could to that or perhaps a solution using procmail or maildrop. For a procmail solution I guess there could be some problems with encoding (perhaps one have to use emil?). Note that the solution should work for multipart encrypted messages (including encrypted attachments) too. Further note that I don't want a discussion about security holes. For me it's ok if messages are stored decrypted on my harddrive (which is encrypted as a whole anyway). In doubt for a first solution it would be ok to store my private key passphrase in cleartext on my harddrive, too. The point is that the mails are encrypted on the mailserver or more generally on their "way through the net".

  • Basic connectivity issues between Win 7 and XP mixed wired/wireless network.

    - by Pulse
    Setup: Windows 7 x64 Ultimate desktop hard wired to Asus WL500gp router (WL500gpv2-1.9.2.7-d-r1445 firmware) Several Bridged VirtualBox VM's running XP, 7, ubuntu server 10.04, Mint 9 and SuSE 11.2 Win XP Pro SP3 notebook with D-Link Airplus wireless network card. No firewall or other security software currently running on either platform (at least for the duration of the test) Situation: Router is acting DHCP server Clients are receiving correct addresses and additional parameters Internet connectivity is available from all clients Windows 7 sharing is set to Network type = work (not home group) NetBT is disabled on all clients using smb over TCP What I can do: I can ping the router and internet addresses from the wireless XP notebook I can ping the Win 7 desktop and any VM from the XP wireless notebook I can ping all devices from the router All VM's and 7 can ping each other and the router as well as Internet addresses What I can't do: I cannot ping the XP wireless notebook from either The Win 7 desktop or the VM's it alwats returns a destination host unreachable. Tracert resolves the name or the XP notebook but also returns a destination host unreachable. From the above it would seem that something is blocking connectivity in a single direction (from the Win 7 box to the Win XP notebook) only but the router can ping the XP notebook. Some fresh input would be most welcome, as this is beginning to drive me batty. Thanks

  • What could cause Windows 7 to hang whenever I install something?

    - by Larsenal
    I've had this problem when installing several different programs (iTunes, Adobe Acrobat Reader just to name two). Regardless of what the program is, the install usually gets at least 90% through the process and then just hangs. I don't see anything bad in the event log besides the following (and this didn't occur exactly at the time of install): wuaueng.dll (964) SUS20ClientDataStore: A request to write to the file "C:\Windows\SoftwareDistribution\DataStore\DataStore.edb" at offset 16252928 (0x0000000000f80000) for 32768 (0x00008000) bytes succeeded, but took an abnormally long time (185 seconds) to be serviced by the OS. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem. I've run check disk and it passed. I've had some problems with BIOS settings in the past with Windows 7, but I'm not sure whether that could be related. Update... I also see this error in the event log: Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. . This is often caused by incorrect security settings in either the writer or requestor process.

I see "Previous versions" of c:\ which look like they correspond to the time of attempted installation.

  • What can I do with a home server?

    - by Joel Coehoorn
    I have an old 700 Mhz Pentium III at home running Windows 2000 Server, with a home router set up to pass incoming requests to it and a DynDNS account set up so it's easy to find. Right now I'm using it for a number of things: Shared folders + backup inside the home network Shared Printer inside the home network Domain Controller, just because I feel like it and because it's useful to me as practice to keep those "enterprise" administration skills. Web Server FTP remote access for my files. I abandoned this for security reasons, but it's still worth leaving visible. Remote Desktop in to the home network (thinking about adding VPN service) SVN repository MySQL - Will be moving to SQL Server 2008 Standard soon. After I upgrade my wife's laptop from home to pro later this year it will also become a domain controller It's the only place I still have access to Internet Explorer 6 any more without setting up a new virtual machine, so I use it for testing code with that browser. The question is: What else could I be doing with this machine? Update Additional ideas based on the suggestions: Media Server/DVR Build server PBX SSH Proxy Server Continuous Integration Server Personal OpenID Provider Update2 Just a note that this server was recently upgraded to an Atom330 with 2 GB ram and bigger hard drive. For all that's slow for a "modern" cpu, it should still be much faster than the old Pentium III and the expected power savings should make the upgrade essentially free over the course of the next year or two. Also, it's now running Windows Server 2008.

  • How do I permanently delete /var/log/lastlog?

    - by GregB
    My /var/log/lastlog file is huge. I know it's really only a few kilobytes, but tar isn't smart enough to know that, so when I image a virtual machine, my restore fails because it thinks I'm trying to load more data than I have capacity on my disk. I want to delete /var/log/lastlog and stop any and all logging to the file. I'm aware of the security implications. This logging needs to stop to preserve my backup strategy. I've made a change to /etc/pam.d/login which I was told would disable logging to /var/log/lastlog, but it does not appear to work as /var/log/lastlog keeps growing. # Prints the last login info upon succesful login # (Replaces the `LASTLOG_ENAB' option from login.defs) #session optional pam_lastlog.so Any ideas? EDIT For anyone interested, I use Centrify Express to authenticate my users via LDAP. Centrify Express is "free", but one of the drawbacks is that I can't manage user UIDs via LDAP, so they are given a dynamic UID when they login to a server. Centrify picks some crazy high UID values (so they don't conflict with local users on the server, presumably). /var/log/lastlog is indexed by UID, and grows to accommodate the largest UID on the system. This means that when a Centrify user logs in, they get a UID in the upper-end of the UID range, which causes lastlog to allocate an obscene amount of space, according to the file system. ~$ ll /var/log/lastlog -rw-rw-r-- 1 root root 291487675780 Apr 10 16:37 /var/log/lastlog ~$ du -h /var/log/lastlog 20K /var/log/lastlog More Into --- Sparse Files

  • Windows service fails to start with local user until password is entered again in logon tab

    - by Nick
    Basically we have a service where we use a local account as its logon. it has all the proper permissions, and everything is working fine, service starts and runs and all is good. Then one day, after rebooting, the service fails to start. Logs show incorrect password. Our technicians resolve the issue by simply retyping the password into the "Log On" tab from the services.msc. Unfortunately we have not been able to root cause. I suspect that the password that is stored for the service is lost somehow. Does anyone know where the password hash might be stored so we can check it? The only activities that seem to be possibly related are patching with Microsoft security patches, but we have multiple servers running the same service, and we have never seen more than one at a time, and its usually a different one each time when this occurrs. I believe this to be the same issue as this: Windows service fails to start with custom user until started once with local user But i was unable to add comments, and its really old.

  • Office Compatibility Pack and File Permissions

    - by hymie
    MS isn't my thing, so I hope somebody can give me a pointer. We have a Windows domain, with a Server-2003-SP1-Enterprise file server. One of the specific files is a MS Excel 2007 (XLSX) file created by user LK. In the "Security" preferences setting, about a half-dozen users (including me) have access to this file. LK is the owner and has "full control", while the rest of us have "Read" , "Read & Execute", and "Write" permission. LK is also the owner of the directory that this file resides in. I don't know if that's relevant. So far so good. My desktop machine has Windows XP SP3 , and Excel 2003 SP3 , and the "Office Compatibility Pack" which lets me read and write the new XLSX files. However, whenever I write the file, the permissions are changed. The newly-written file only has permissions for LK and me, and both are "Full control" So in short, what am I doing wrong, and how should I set this up to do it right, keeping the permissions on the file that were there when I started?

  • A little guidance setting up FTP server authentication on Windows Server 2008 R2 standard?

    - by Ropstah
    I have a (clean) server running Windows Server 2008 R2 standard. I would just like to use it for serving a website and a FTP server through IIS. IIS is installed and serves my website propery. I have now added a FTP site but when I try to logon using my user/pass i get the following error: 530 User cannot login From this article (http://support.microsoft.com/kb/200475) I understand that these four causes can be pointed out: The Allow only anonymous connections security setting has been turned on in the Microsoft Management Console (MMC). Not the case The username does not have the Log on locally permission in User Manager. The user is in the Users group, however I'm not able to logon through RDP. I tried configuring this by following this article through GPMC however this only works when I'm logged in as a domain user on a domain controller which I'm not: I'm logged in as administrator The username does not have the Access this computer from the network permission in User Manager. Not sure what this implies...? The Domain Name was not specified together with the username (in the form of DOMAIN\username). Tried adding the server name: server\username, not working... I am an absolute server noob and I'd just like to be able to connect through FTP... Any guidance is highly appreciated!

  • Why does my microwave kill the Wi-Fi?

    - by Ohlin
    Every time I start the microwave in the kitchen, our home Wi-Fi stops working and all devices lose connection with our router! The kitchen and the Wi-Fi router are in opposite ends of the apartment but devices are being used a little here and there. We've been annoyed by the instability of the Wi-Fi for some time and it wasn't until recently we realized it was correlated to microwave usage. After some testing with having the microwave on and off we could narrow down the problem to only occurring when the router is in b/g/n mode and uses a set channel. If I change to b/g mode or set channel to auto then there is no problem any more...but still! The router is a Zyxel P-661HNU ("802.11n Wireless ADSL2+ 4-port Security Gateway" with latest firmware) and the microwave is made by Neff with an effect of 1000W (if this information might be useful to anyone). There is an "internet connection" light on the router and it doesn't go out when the interruption occurs so I think this is only an internal Wi-Fi issue. Now to my questions: What parts of the Wi-Fi can possibly be affected by the microwave usage? Frequency? Disturbances in the electrical system? How can setting Auto on channels make a difference? I thought the different channels were just some kind of separation system within the same frequency spectrum? Could this be a sign that the microwave is malfunctioning and slowly roasting us all at home? Is there any need to be worried? Since we were able to find router settings that cooperate well with our microwave's demand for attention, this question is mainly out of curiosity. But as most people out there...I just can't help the fact that I need to know how it's possible :-)

    - by afifio
    Hi and thanks for stopping by. I have read Weird Apache problem with file, I have read Weird Apache problem with file ...and its not the problem Setup single XAMPP installation on Windows, single windows user, 2HD, 1 is a portable USB. All is fine, until I move the xampp to new portable HD Symptom Old php files - works fine, new one doesnt http://127.0.0.1/Ajax/index.php - yay http://127.0.0.1/test2/t.php - display the source code http://127.0.0.1/Ajax/test2/t.php - display the source code http://127.0.0.1/Ajax/t.php - display the source code Extra Info IIS+MS Web Development stuff, .NET4, Asp, etc is being installed and still hast reboot yet. .htaccess also seems doesnt work Apache2 conf file was modified to Averride All and still it doesnt care. One of the directory supposed to treat .htm as php yet got text, created another directory and edit a phpinfo, still another text, browse to phpmyadmin, viola, works fine Suspect Does Apache honour XP security and permission ? If so, this is a single user computer. Does Apache dont like my new hard disk/new place ? Why it doesnt execute the php in new directory but happily execute in old folder ? Thanks for the riddle answers

  • choosing hosting for custom ecommerce site, shared, dedicated, what to look for?

    - by spirytus
    Hi, I have (almost) developed website for my client and now need to decide on hosting. Most of the users of the site will be located in Australia, and so am I and my client. Now, I want to consider everything before deciding on host and few questions comes to my mind: I cannot afford website being down, and all hosts say something like "99% uptime guranted". Should just that be enough or shall I ask hosts for some stats maybe? Does it make any difference if servers and whole hosting company is located in Australia or outside? I've been hosting few sites with JustHost.com on shared hosting (cheapest plan, servers in US I believe) and never seen any delays but could that be an issue? I would prefer Australian company so I can actually go to them and give them piece of my mind if something goes wrong, but US servers seem cheaper. Would share hosting do? Its ecommerce custom build php application, I know there are security issues with sessions etc on shared hosting. Will take precautions of course but could share hosting be an issue? Would dedicated be worthy option considering that my knowledge of server is very limited? I need to run php/mysql, with preferably unlimited bandwidth as with my experience I cannot tell what amount of traffic would be sufficient. Please let me know if I didn't provide you with enough information so you could answer my questions, will gladly explain further. In advance thanks for any answers :)

  • Enter network credentials as part of batch script

    - by Michael
    WinXP: I have several system services that are needed to run some machinery in my lab. The machine these services are running uses a lab login that has administrator rights. Our IS department, unfortunately, has it set up where at some point during the night the login "loses" the privilege level to start/stop these services. The account stays logged in, but the software controlling my hardware becomes unresponsive. In order to get things back up and running, I have to stop the system services and restart them. Because of the security settings, however, I have to re-enter the user password to start the service (even though the user was never logged out). That, I get the "This service cannot be started due to a logon failure" and I have to enter the password. What would be ideal is to have a batch script run before anyone gets into work that stops all of the necessary services, enters the user credentials when prompted, and then restarts them so that everything is ready for first shift to run. I assumed that using the Task Scheduler in Windows would work as it allows you to run batch files with a user's name and password, but this didn't seem to do the trick. With this setup I would arrive to find that all the services are stopped but not started again. (Presumably because the authentication failed.) The batch file is about as simple as it gets, all I have is: net stop "Service1" net stop "Serivce2" etc., then restart in reverse order based on dependency: net start "Service2" net start "Serivce1" What would it take to accomplish what I'm trying to do and restart the services?
