    Join New PC to Server

    Verified

    I have a brand-new Windows workstation that is on our office Ethernet but still sitting outside the domain and blocked from the built-in administrator account. The rest of the network is healthy—only this one machine is having trouble—so I need someone who can jump in, join it to the network, and prove that it talks to our server without errors. Here’s what I expect to be wrapped up during the session: • Sign in with the built-in administrator, clear the “access denied” roadblock, and confirm full local control. • Configure the NIC, DNS, gateway, and any other settings needed, then join the correct domain (or workgroup, if that turns out to be the better fit). • Verify that mapped drives, shared folders, and line-of-business apps are re...

    My DirectAdmin server hosts several domains whose SSL certificates are about to expire, and the automatic renewal process keeps throwing errors. I need a professional who already knows the quirks of DirectAdmin to step in, diagnose why the renewal is failing, and get every domain back to a clean, padlock-green state. Here’s what I expect: • All current certificates renewed (Let’s Encrypt or existing CA, whichever is appropriate) for every domain on the server. • Verification that each site loads over HTTPS without browser warnings. • Any mis-configured redirects or mixed-content issues resolved so the lock icon stays solid. • A short, plain-English note explaining what was fixed and how future renewals will run smoothly. Please tell me about your h...

    I already have Proxmox VE 9 installed on an OVH dedicated box; I now need an experienced hand to bring the deployment to production-ready status. The job centres on three areas: • Storage – carve up the local disks into a resilient ZFS pool and document the exact pool layout and scrub schedule. • Networking – create a clean bridged setup with VLANs so that I can segment guests appropriately while keeping OVH’s network expectations intact (failover MACs, gateway handling, etc.). • Security – activate and tune Proxmox’s built-in firewall rules, lock down SSH, and ensure the web console is reachable only from my chosen WAN IPs or over Tailscale/another lightweight VPN. When the work is finished I expect a short, step-by-step write-up detailin...

    I need my FortiGate 60 appliance configured so that staff from three separate groups can log in over a Remote Access VPN. Each group belongs to its own user group and must see only the resources assigned to it; nothing should bleed across locations. I will be using straightforward username-and-password authentication for every account. You’ll create the necessary address objects, user groups, policies, and split-tunnel settings so that: • Group A reaches the resources in Location A • Group B reaches the resources in Location B • Group C reaches the resources in Location C Please prepare the FortiClient VPN profile settings I can distribute to users and document any firewall or routing changes you make so I can maintain them later. All work must be done on th...

    I’m putting together a new publication and need an experienced creative partner who can guide the entire process—from shaping the concept to delivering press-ready files. I’m still open on the exact format, so whether the final piece becomes a book, magazine, or brochure will depend on what best serves the content and audience we define together. Scope of work • Help me refine the publication’s purpose and target readers. • Recommend the most suitable format and page count. • Develop an editorial structure and visual style guide. • Create engaging content (articles, photos, illustrations) or coordinate with contributors as needed. • Design clean, modern layouts that balance readability with strong visual appeal. • Prepare fin...

    I’ve installed a Hirschmann EAGLE40 industrial firewall and now need a specialist to walk it from factory defaults to a production-ready state. The hardware is racked, powered, and reachable through both the web interface and SSH; what’s missing is a solid rule-set, proper interfaces, and clean logging so the device actually protects the plant network rather than just sitting in the traffic path. Here’s what I expect: • You review the current blank configuration, discuss my network layout, and translate that into interface zones, NAT (if required), and a concise set of access rules. • You advise on best-practice hardening for an EAGLE40—admin account lockdown, firmware verification, logging to our Syslog server, and fail-safe settings. • You loa...

    I run a computer-centric business that relies on a hybrid setup—part cloud, part on-prem servers—and I need a reliable partner to keep everything humming. Day-to-day, the help I’m after centers on two fronts: tracking down and fixing software glitches before they hurt productivity, and handling the nuts-and-bolts upkeep of our desktops, laptops, printers, and the small server room we still operate. Here’s what that looks like in practice: • Software troubleshooting: isolate crashes, apply patches, resolve compatibility issues across Windows and Linux, and speak with vendors when escalation is required. • Hardware maintenance: swap failing parts, run preventive diagnostics, clean equipment, and advise when a full replacement is more cost-effective. I r...

    I’m looking for a marketing partner who can help me lift my brand’s visibility. My priority is marketing (not customer service or education) and the specific objective is to increase brand awareness. To make that happen, I want to concentrate on three complementary channels—social media, email marketing, and content marketing (blogs and articles). Here’s what I need: • A clear, data-backed strategy for how these three channels will work together to reach new audiences. • An editorial and posting calendar that keeps campaigns consistent and on message. • Attention-grabbing social posts, well-crafted email sequences, and authoritative blog or article content that all share a unified voice. • Ongoing performance tracking with concise report...

    After moving my sites from RamNode’s cloud hosting to a new VPS, several core services stopped working. WHM and cPanel are installed and accessible, yet there were issues with the site. I changed the mailservers back to cloud hosting. What I need right now is a full review and clean configuration of the server so every component—mail server, FTP service, and DNS including nameserver glue—operates smoothly. Please log in, audit each service, adjust the settings, and document any permanent changes you make. Before I repoint the real nameservers, show me a working preview link or temporary hostname that proves the sites load correctly and email delivers both ways. Please also help me verify the glue records through WHOIS, so include that in your checklist. Deliverable for...

    I have a fresh Proxmox installation in place and now need an experienced hand to complete the next step: configuring a set of Linux-based virtual machines from the ground up. Your job is to handle the full system setup and configuration workflow—networking, storage assignment, template creation, and any tweaks required so the VMs boot cleanly and are ready for application deployment. Please bring solid, demonstrable experience with the Proxmox VE interface, CLI utilities, and typical KVM/QEMU guest-optimisation practices. Once you’re done I expect: • A working pool of Linux VMs (Debian or Ubuntu preferred, but I’m open to other mainstream distros if you recommend them) • Basic resource limits, bridge/VLAN networking configured, and a brief hand-over note exp...

    Fix Linux Server Packet Loss
    1 day left
    Verified

    I’m facing persistent outbound packet loss on my Linux server. The problem appeared a few days ago, right after I upgraded my hosting plan, and it has started to affect production-level traffic. Latency is acceptable and inbound packets arrive cleanly; only the outbound stream is dropping frames. I need someone who can jump in immediately, trace the root cause, and apply a permanent fix. Typical tools for the job might include tcpdump, traceroute, iptables, nftables, netstat, or any monitoring utilities you prefer—as long as the solution is clearly explained and reproducible. Acceptance criteria: • Outbound traffic shows 0 % (or normal-range) packet loss under load tests. • A short summary of what was wrong and the exact commands or configuration changes you app...

    I manage a small group of VIP users who expect white-glove treatment whenever something goes wrong. Their day-to-day pain points fall into two buckets: • Software installation and configuration: from first-time deployments to tricky patching and plugin conflicts across Windows and macOS. • Connectivity hiccups—specifically frequent disconnections or an outright inability to join the network. I’ll route tickets to you through our help-desk portal (ServiceNow), and you will step in remotely via RDP, AnyDesk or VPN, diagnose, resolve, then document the fix in our knowledge base so the same issue never reaches the escalation queue twice. Clear, jargon-free status updates to the VIP are essential; I measure success by resolution time, user satisfaction scores and clean...
