The user cannot access a specific website that their colleagues can access, despite trying different browsers and clearing their cache. They suspect a DNS or firewall issue.

قد تكون إعدادات DNS لجهاز الكمبيوتر الخاص بك غير صحيحة أو غير قادرة على حل اسم نطاق الموقع إلى عنوان IP الخاص به. هذا أمر شائع إذا كان ذاكرة التخزين المؤقت لنظام أسماء النطاقات المحلي لديك تالفة أو إذا كان خادم DNS الذي قمت بتكوينه يواجه مشكلات.
قد يتعرف جدار الحماية أو برنامج مكافحة الفيروسات على جهاز الكمبيوتر الخاص بك عن طريق الخطأ على الموقع كتهديد ويمنع الوصول إليه. يمكن أن يحدث هذا بسبب تعريفات قديمة أو إعدادات أمان مفرطة.
إذا كنت على شبكة مؤسسية، فقد يقوم جدار حماية على مستوى الشبكة أو خادم وكيل بحظر الوصول إلى الموقع الإلكتروني. غالبًا ما يتم ذلك لأسباب أمنية أو لتصفية المحتوى.
قد يكون عنوان IP المحدد للموقع محظورًا في ملف 'hosts' المحلي لديك أو بواسطة إضافة للمتصفح. هذا أقل شيوعًا ولكنه ممكن إذا تم إجراء تكوينات يدوية.
🤖 AI Analysis
"The user is on a company network and colleagues can access the site. This strongly suggests a network-level restriction or configuration issue managed by the company's IT department. The 'Page not found' error, combined with colleagues' access, points to a potential block or misconfiguration on the company's network."
🤖 AI Analysis
"Since the user is on a company network, it's possible that the company's firewall or antivirus software is blocking access to the website. Temporarily disabling it can help diagnose this. However, it's less likely than a network-wide restriction managed by IT."
🤖 AI Analysis
"Similar to disabling the firewall/antivirus, if these are indeed the cause, adding an exception would resolve the issue. This is a more targeted approach than disabling entirely."
🤖 AI Analysis
"The 'Page not found' error could indicate a DNS resolution issue or an incorrect IP mapping in the hosts file. While less common for a single website on a company network, it's a possibility that should be checked."
🤖 AI Analysis
"Changing DNS servers can resolve 'Page not found' errors if the company's internal DNS is having issues resolving the specific website. This is a plausible step, especially if the company's DNS is misconfigured or outdated for that particular domain."
🤖 AI Analysis
"Flushing the DNS cache can resolve issues where the computer has outdated or incorrect DNS information for a website. This is a standard troubleshooting step for 'Page not found' errors."
🤖 AI Analysis
"Browser extensions can sometimes interfere with website loading. While the problem is specific to one website and others can access it, it's a quick step to rule out browser-specific issues."
🤖 AI Analysis
"Using a VPN could bypass network restrictions, but the user is already on a company network, and using a personal VPN might be against company policy. If the company has its own VPN, that's a different scenario, but the problem description doesn't suggest that. It's a less direct solution given the context."
